Dimensional Analysis in Physics Problems

Dimensional Analysis in Physics Problems Dimensional analysis is a method of using the known units in a problem to help deduce the process of arriving at a solution. These tips will help you apply dimensional analysis to a problem. How Dimensional Analysis Can Help In science, units such as meter, second, and degree Celsius represent quantified physical properties of space, time, and/or matter. The International System of Measurement (SI) units that we use in science consist of seven base units, from which all other units are derived. This means that a good knowledge of the units youre using for a problem can help you figure out how to approach a science problem, especially early on when the equations are simple and the biggest hurdle is memorization. If you look at the units provided within the problem, you can figure out some ways that those units relate to each other and, in turn, this might give you a hint as to what you need to do to solve the problem. This process is known as dimensional analysis. A Basic Example Consider a basic problem that a student might get right after starting physics. Youre given a distance and a time and you have to find the average velocity, but youre completely blanking on the equation you need to do it. Dont panic. If you know your units, you can figure out what the problem should generally look like. Velocity is measured in SI units of m/s. This means that there is a length divided by a time. You have a length and you have a time, so youre good to go. A Not That was an incredibly simple example of a concept that students are introduced to very early in science, well before they actually begin a course in physics. Consider a bit later, however, when youve been introduced to all kinds of complex issues, such as Newtons Laws of Motion and Gravitation. Youre still relatively new to physics, and the equations are still giving you some trouble. You get a problem where you have to calculate the gravitational potential energy of an object. You can remember the equations for force, but the equation for potential energy is slipping away. You know its kind of like force, but slightly different. What are you going to do? Again, a knowledge of units can help. You remember that the equation for gravitational force on an object in Earths gravity and the following terms and units: Fg G * m * mE / r2 Fg is the force of gravity - newtons (N) or kg * m / s2G is the gravitational constant and your teacher kindly provided you with the value of G, which is measured in N * m2 / kg2m mE are mass of the object and Earth, respectively - kgr is the distance between the center of gravity of the objects - m  We want to know U, the potential energy, and we know that energy is measured in Joules (J) or newtons * meter  We also remember that the potential energy equation looks a lot like the force equation, using the same variables in a slightly different way In this case, we actually know a lot more than we need to figure it out. We want the energy, U, which is in J or N * m. The entire force equation is in units of newtons, so to get it in terms of N * m you will need to multiply the entire equation a length measurement. Well, only one length measurement is involved - r - so thats easy. And multiplying the equation by r would just negate an r from the denominator, so the formula we end up with would be: Fg G * m * mE / r We know the units we get will be in terms of N*m, or Joules. And, fortunately, we did study, so it jogs our memory and we bang ourselves on the head and say, Duh, because we should have remembered that. But we didnt. It happens. Fortunately, because we had a good grasp on the units we were able to figure out the relationship between them to get to the formula that we needed. A Tool, Not a Solution As part of your pre-test studying, you should include a bit of time to make sure youre familiar with the units relevant to the section youre working on, especially those that were introduced in that section. It is one other tool to help provide physical intuition about how the concepts youre studying are related. This added level of intuition can be helpful, but it shouldnt be a replacement for studying the rest of the material. Obviously, learning the difference between gravitational force and gravitational energy equations is far better than having to re-derive it haphazardly in the middle of a test. The gravity example was chosen because the force and potential energy equations are so closely related, but that isnt always the case and just multiplying numbers to get the right units, without understanding the underlying equations and relationships, will lead to more errors than solutions.

Gunpowder Facts, History and Description

Gunpowder Facts, History and Description Gunpowder or black powder is of great historical importance in chemistry. Although it can explode, its principal use is as a propellant. Gunpowder was invented by Chinese alchemists in the 9th century. Originally, it was made by mixing elemental sulfur, charcoal, and saltpeter (potassium nitrate). The charcoal traditionally came from the willow tree, but grapevine, hazel, elder, laurel, and pine cones have all been used. Charcoal is not the only fuel that can be used. Sugar is used instead in many pyrotechnic applications. When the ingredients were carefully ground together, the end result was a powder that was called serpentine. The ingredients tended to require remixing prior to use, so making gunpowder was very dangerous. People who made gunpowder would sometimes add water, wine, or another liquid to reduce this hazard since a single spark could result in a smoky fire. Once the serpentine was mixed with a liquid, it could be pushed through a screen to make small pellets, which were then allowed to dry. How Gunpowder Works To summarize, black powder consists of a fuel (charcoal or sugar) and an oxidizer (saltpeter or niter), and sulfur, to allow for a stable reaction. The carbon from the charcoal plus oxygen forms carbon dioxide and energy. The reaction would be slow, like a wood fire, except for the oxidizing agent. Carbon in a fire must draw oxygen from the air. Saltpeter provides extra oxygen. Potassium nitrate, sulfur, and carbon react together to form nitrogen and carbon dioxide gases and potassium sulfide. The expanding gases, nitrogen and carbon dioxide, provide the propelling action. Gunpowder tends to produce a lot of smoke, which can impair vision on a battlefield or reduce the visibility of fireworks. Changing the ratio of the ingredients affects the rate at which the gunpowder burns and the amount of smoke that is produced. Difference Between Gunpowder and Black Powder While black powder and traditional gunpowder may both be used in firearms, the term black powder was introduced in the late 19th century in the United States to distinguish newer formulations from traditional gunpowder. Black powder produces less smoke than the original gunpowder formula. Its worth noting early black powder was actually off-white or tan in color, not black! Charcoal Versus Carbon in Gunpowder Pure amorphous carbon is not used in black powder. Charcoal, while it contains carbon, also contains cellulose from incomplete combustion of wood. This gives charcoal a relatively low ignition temperature. Black powder made from pure carbon would barely burn. Gunpowder Composition There is no single recipe for gunpowder. This is because varying the ratio of the ingredients produces different effects. Powder used in firearms needs to burn at a fast rate to quickly accelerate a projectile. A formulation used as a rocket propellant, on the other hand, needs to burn more slowly because it accelerates a body over a long period of time. Cannon, like rockets, use a powder with a slower burn rate. In 1879, the French prepared gunpowder using 75% saltpeter, 12.5% sulfur, and 12.5% charcoal. The same year, the English used gunpowder made from 75% saltpeter, 15% charcoal, and 10% sulfur. One rocket formula consisted of 62.4% saltpeter, 23.2% charcoal, and 14.4% sulfur. Gunpowder Invention Historians believe gunpowder originated in China. Originally, it was used as an incendiary. Later, it found use as a propellant and explosive. It remains unclear when, exactly, gunpowder made its way to Europe. Basically, this is because records describing the use of gunpowder are difficult to interpret. A weapon that produced smoke might have used gunpowder or could have used some other formulation. The formulas that came into use in Europe closely matched those used in China, suggesting the technology was introduced after it had already been developed. Sources Agrawal, Jai Prakash (2010).

Leadership in Film Honor and Glory - Essay Example It speaks about the horrors, rigors and racism of men crossing the North Pole. The basically unknown story of Matthew Henson who has almost been forgotten from history as the co-discoverer of the North Pole simply because of his race. Delroy Lindo gives an excellent portrayal of Matthew Henson who's ability to co-habitat and communicate with the natives allows he and Perry to reach what was once unreachable. Our nation has great discovers and inventors who should not simply be forgotten because they were of a different race. The struggle and anonymity Matthew Henson endured after his trek should never have happened. This movie does a very good job in reminding us that we are a nation of adventurers.. Black and White. History, the saying goes, is written by the winners. As the melancholy English poet Thomas Gray eulogised in his mid-17th century poem "Elegy in a County Churchyard," there is a vast wealth of unrealised human potential resting six feet beneath our feet. How many Miltons and Shakespeares, he asked, have passed us by because of a rigid and unforgiving social system that refused to allow those of humble birth to rise above their station Textbooks happily proclaim that American Admiral Robert Peary discovered the North Pole, but how many of these same books tell the story of the other American who a

EU LAW - Essay Example As such, Lord Denning stated that EC law was directly applicable at national level under domestic law. However, the term â€Å"directly applicable† has created ambiguity and the principles of direct effect and indirect effect will determine whether the Council Directive relating to the right of consumers to full contract price refunds (the Directive) is directly applicable under UK law4. If a provision of EC law is directly applicable, section 2(1) of the ECA asserts that â€Å"all such rights, powers, liabilities, obligations and restrictions†¦Ã¢â‚¬ ¦ shall be recognised and available in law, and be enforced, allowed and followed accordingly.† The current scenario is concerned with the failure to implement the Directive and this analysis will review whether Christina can enforce the rights she would have had if the Directive had been implemented under the doctrine of direct effect; or alternatively, what her rights are against the state for damage suffered as a result of failure to implement the Directive. The specific nature of directives lies in the type of obligations they impose5. Ultimately Member States have discretion as to how to implement a directive, however they must comply with the positive obligation to implement the directive in the first place6. Problems have arisen as to whether Directives themselves can be invoked by individuals in national courts as giving rise to individual rights7, further compounded by the question as to whether a Member State can be liable for damage resulting from its failure to implement a directive, which is pertinent to Christina’s position. In order to be directly effective, a provision of EC law must constitute a complete legal obligation capable of enforcement as such by a court8. Moreover, in the case of Francovich v Italian Republic9, it was asserted that the pre-requisite for direct effect

The treaty of Versailles Essay Example for Free

The treaty of Versailles Essay The treaty of Versailles caused a reaction of horror and outrage to the Germans. They were being forced to accept a harsh treaty without any choice or even a comment. Hitler hated the treaty of Versailles, and he promised to kick out the treaty of Versailles as he had said in the Nazis Twenty-Five Points. People began to believe in Hitler. His Twenty-Five Point programme showed that the treaty of Versailles could be dealt as any other task, and he promised to abolish it right away. The treaty of Versailles was the most important of the Long-term causes because it gave Hitler the opportunity to share the same ideas as the Germans about the treaty of Versailles. So he took advantage in the middle of a politically destabilized Germany. Short-term causes like the Munich Putsch helped his popularity, which was essential to his rise to power. The Munich Putsch was a disaster for Hitler. People didn’t t rise to support him. Hitler was arrested and charged with treason. In trial, Hitler gained lots of publicity and his ideas were reported in newspapers. Hitler convinced the judges, and got five years in prison instead of a life sentence, but Hitler served only nine months in prison. This concludes that Hitler gained lots of publicity with the Munich Putsch. His ideas were printed on Newspaper, so more and more Germans began liking Hitler’s ideas and voted for him. Other Short-term causes like the Enabling law meant that Hitler had total power over Germany. After being elected chancellor there was nothing anyone else could do not even Hindenburg. He was able to pass laws for the next four years without consulting the Reichstag. Hitler used the power of the Enabling Law to get rid of anything or anyone that limited his authority. Hitler made all sorts of laws. Hitler was completely untouchable. The Weimar Republic was destroyed as an outcome of the Enabling Law. Both long and short term causes in Hitlers rise to power are important. Hitlers wanted revenge over his hatred of the Treaty of Versailles which he said must be torn up. Without this Hitler would have no reason to get into politics and start his journey to power. The economic depression also helped Hitlers rise to power because Germany was vulnerable and the Weimar rebublic had no idea how to solve the problems. People looked for an alternative government that they found in the Nazi party. ≠¤ Although I have already explained how the depression contributed to Hitlers rise to power he may not have had the political knowledge to succeed if it werent for the Munich Putsch several years earlier, which had a short term impact on Germany but a long term effect on Hitlers understanding as he now knew how to destroy democracy using democracy. To sum up, each cause was needed for Hitlers rise to power and many short term causes wouldnt have happened without the long term ones being set in place first. QUESTION #3 The Treaty of Versailles was important to Hitlers rise to power because, it was the cause of Germanys downfall. Hitler felt very strongly about the Treaty of Versailles and thought the terms were unfair towards Germany. Many German people also despised the treaty, and wanted something done about it. Hitler was there to turn to. He wanted to abolish the treaty and all of it terms. Consequently the Treaty of Versailles helped to cause the Economic depression, in Germany. Meaning that the treaty and theeconomic depression were both linked together strongly, because the treaty told Germany to pay reparation bills, around ?6600 million to the countries they damaged during World War 1. Which meant that Germany did not have much money left for it. This caused the start of the economic downfall, among other issues. This was extremely important to Hitlers rise to power, as it enabled him to help the German people and use his oratory skills to impress people with his words and won the nations heart. The economic depression, 1923 1929 is linked with Hitlers oratory, personality and leadership. Although it applies more to the economic disaster of 23 because at this time the German people needed someone to turn to for help and Hitler offered to take them over as someone to lead them to a better Germany, Hitler states some ideas for example the abolition of the Treaty of Versailles and the union of Germany and Austria. These were popular as a lot of Germans also agreed. In my opinion this was the biggest influence to Hitlers rise to power, because all the causes on the list used Hitlers oratory, personality and leadership skills. Hitlers oratory and personality came in to use most in the Munich Putsch situation, when Hitler used his skills to deal with the mess he got in to. He was charged and arrested for treason after hijacking a government meeting and taking over the government of Bavaria. It is linked because in Hitlers trial he impressed the judges so much they only sentenced him to 9 months instead of the normal life sentence. This was important to Hitler if he wouldnt had have been such a great speaker then he would have never had a chance to rule over Germany as well as all the publicity. * All of the reasons on the list were important for Hitler to rise to power in the way that he did. However, even then some reasons are more important than others. Therefore, it is necessary to see which factors were important not only in the way in which he did rise to dictatorship, but also whether Hitler could have risen to power in any other way either with or without some of the factors on the list. Therefore, the Treaty of Versailles was the most important reason on the list to explain why Hitler rose to absolute power in Germany, when he did, how he did, and above all that without it he would have gone into politics but remained a fringe party. The desire in Hitler and others around him was one of the most important reasons why Hitler joined politics. He felt that his country had been betrayed by the NovemberCriminals and that the Treaty of Versailles was too harsh and unfair considering many believed that the German army was still unbeaten. Despite all of this, the Treaty of Versailles was also the most important reason on the list because it was so unfair and because of some of the terms for peace which it stipulated. The main problem was the great loss of German land to other countries and the loss of Germanys industrial heartlands in addition to the great level of reparations. The reparations, which were a result of the Treaty of Versailles and the War Guilt clause, started all of the other factors on the list. If the German people and the army had not felt angered by their treatment under the treaty, they would not have been dissatisfied with the victors of the war, and would not have felt so great a desire for revenge. The Weimar Republics weakness also stemmed from its link to defeat and never had enough power or support to succeed. If the Weimar Republic had not been so weak, hyperinflation would not have occurred and the reparations would have not affected them as much. Without the hyperinflation and the inability to pay reparations, France would not have invaded the Ruhr, which sparked off the Munich Putsch. Furthermore, without reparations the depression would not have hit Germany so badly because they would have been less dependent * The Treaty of Versailles was important to Hitlers rise to power because, it was the cause of Germanys downfall. Hitler felt very strongly about the Treaty of Versailles and thought the terms were unfair towards Germany. Many German people also despised the treaty, and wanted something done about it. Hitler was there to turn to. He wanted to abolish the treaty and all of it terms. Consequently the Treaty of Versailles helped to cause the Economic depression, in Germany.

These were popular as a lot of Germans also agreed. In my opinion this was the biggest influence to Hitlers rise to power, because all the causes on the list used Hitlers oratory, personality and leadership skills. * The causes in Hitler’s rise to power may be established in terms of importance, that is how much they contributed to the eventual result. I shall start by choosing a particular reason which I feel to be most important and establish links with other causes from this, although my analysis could change my outlook on the idea of superiority of one cause over another. I have chosen Hitler’s oratory, personality and leadership (OPL) to be the most important cause. Hitler’s OPL was both long term and sustained consistency and were often used to great effect for varying situations. In court, following the Munich Putsch, Hitler was on the sidelines, and seemed inevitable to a heavy prosecution, although a determined oratory along with a characteristic personality won many over and Hitler was significantly let off the hook. Similarly, before many of the ‘causes’ expressed for his rise, had it not been for a rallying personality, and a strong-minded personality during his first meeting with the German Workers Party, Hitler would never have created the future of events, such as the Munich Putsch, and the future of Germany could have been very different. Had it not been for many of these skills, he would not been able to capitalise on opportunities in the unique way that he did, for example, a determined personality with an interest for the country following the economic depression allowed propaganda to gain him vast support, and were it not for an oratory in his style, many of the arguments could have sounded feeble and unconvincing; as emotions were commonplace in speeches. Thus, the point made is that the very means, by which Hitler tackled situations and the outcomes it gave, are central to these skills in oratory, personality and leadership, and without them, Hitler may never have seriously been considered the dictator he became. Hitler’s oratory, personality and leadership may be linked to theeconomic depression, as they have strong connections.

Sustainable Agriculture: The Ethical Choice for the Future Essay

Sustainable Agriculture: The Ethical Choice for the Future Thesis: The idea of sustainable agriculture is a legitimate, logical, and necessary approach to the new concerns and problems stemming from current agricultural trends in light of impending global food shortages and rapid depletion of natural resources. Introduction Agriculture has been a principal source of obtaining food to meet basic needs of humans for thousands of years. More recently, with the industrialization of agriculture, increased efficiency, and a decreased need for small rural farmers, there has been a resulting disconnect of consumers to the process in which their food is produced. As we are embarking on a new century, there is growing concern that perhaps our industrialized agriculture system is not functioning as effectively as it has in the past. It is time that we move to adopt a new paradigm as we realize the effects of modern agriculture on our environment, economic viability, and social justice issues, in light of the impending global food shortage. According to John Ikerd from the University of Missouri, traditional agriculturists currently foresee a continued trend toward fewer, larger, and more specialized production units. They see current trends continuing until a half-dozen or so multinational corporations control vir tually all processing and distribution of agricultural commodities in a single global food and fiber market.

Henry David Thoreau †“Why I Went to the Woods” Essay

This excerpt is from his famous essay, â€Å"On the Duty of Civil Disobedience†. First, some background; in 1842, his brother John died of lockjaw. Three years later, Henry decided to write a book commemorating a canoe trip he had taken with John in 1839. Seeking a quiet place to write, he followed a friend’s suggestion and built a small cabin on the north shore of Walden Pond on a piece of land owned by his friend and mentor, Ralph Waldo Emerson. He started work on his cabin in March of 1845. On the 4th of July, he moved in. Thus began one of the great and lasting experiments in life and thought of the whole of human experience. â€Å"I went to the woods because I wished to live deliberately, to front only the essential facts of life, and see if I could not learn what it had to teach, and not, when I came to die, discover that I had not lived.† Thoreau otherwise filled his time by working in his garden, talking with visitors, reading, and writing in his diary. B ut most of all, he walked and thought, and it’s difficult to tell now which was the more important activity. It seems that, in his two years living in his little cabin in the woods he brought himself to a state of conscious living, where thought and action were harmoniously combined. This story is about his rejection of the world’s definition of ‘success’ and so he demanded a life of personal freedom. He went to the woods, built a humble cabin on the edge of Walden Pond, Concord, Massachusetts†¦and learned about nature and life. He rejected the Establishment and all its trappings. He saw such possessions as fancy clothes and elaborate furniture as so much extra baggage. He demanded a fresh, uncluttered existence with time for self-exploration. He would, he told the world, â€Å"breathe after his own fashion.† All aspects of life for Thoreau focused on simplicity. When Thoreau’s two years at Walden had ended, he left with no regrets: â€Å"I left the woods for as good a reason as why I went there. Perhaps it seemed to me that I had several more lives t o live, and could not spare any more time for that one . . . â€Å" His experiment had been a success. Thoreau had learned many lessons, had taken time to examine his inner self and his world, and proved he could live under the simplest conditions and still be fulfilled: â€Å"I learned this, at least, by my experiment; that as one advances confidently in the direction of his dreams, and endeavors to live the life which he has imagined, he will meet with a success unexpected in common hours.† To him, most men live lives of â€Å"quiet desperation,† and have needed to simplify, to cast off material  encumbrances and achieve true freedom. The stages of spiritual evolution that a man passes through all prepare him for the more difficult inner development; and every man, he believed, possesses an inner spiritual instinct which, if nurtured and cared for, will divulge his divine nature.

Nature and Nurture Influences Essay

We were asked to write a paper on Nature and Nurture influences on a child development. There has been a debate for years about this topic. Some phycologist believe that it is just nature that you are born with the genes from you parents to make you the way you are through evolution. Then there are those that it is just the nurturing we receive as babies or even in the womb through our child hood. That both Nature and Nurture go together in some way. The difference between Nature and Nurture will be described and the relationship between the two. I will explain the biological, environmental, societal, and cultural influences on child development in relation to nature versus nurture. This debate has gone one since 1970’s, when some studies showed the social behaviors of primates like chimpanzees and gorillas that this was humans closest relatives genetically speaking (Garcà ­a, J. 2014). The increased social significance of gay and lesbian rights in recent years has sparked in terest among some researchers as to the causes of homosexuality. Supporters of gay rights claim that homosexuality is natural and innate, while many opponents of gay rights often claim that homosexuality is a lifestyle choice (Garcà ­a, J. 2014). These are big debatable topics that they say is all nature. I disagree I am a Christian and go by the bible not scientist sorry that’s my belief. Whether you are gay or believe we come from monkeys that’s fine. I believe it is a choice you choose to be the way you are it’s your life style that’s fine. We are nurtures from the time we are conceived parents talk to their babies will in the womb. The fetus does respond to noise we say the ABC’s to them when they are born we hold them feed them. When our children get older or fall as a child we kiss their wounds to make them feel better. We teach them to ride bikes some grasp it faster than others we  encourage our children to do their best in everything they do. I have four children they are all different the pregnancies was different. My pregnancies with my sons I was not sick with either. First child sleep great hardly sick. The second pregnancy my son was sick for the first year had colic ear infe ctions was rough. The pregnancies with my girls I was sick had acid reflux in the beginning of the third pregnancy fourth was a girl acid reflux during my whole pregnancy. They both had it in the beginning as well, but my youngest daughter still have attacks of acid reflux. Not everything is genetic we get our looks from our parents some are great musicians, but their child doesn’t follow their footsteps and can play any instrument. I peck a piano my daughter taught herself other children do not know how to play. Factor, in the study of development, nature refers to the inherited (genetic) characteristics and tendencies that influence development. Nurture affects children’s development through multiple channels: physically through nutrition, activity, and stress; intellectually through informal experiences and formal instruction; and socially through adult role models and peer relationships. In contrast, abilities in traditional school subject areas (e.g., reading, geography) and advanced artistic and physical skills (e.g., playing the piano, playing competitive soccer) rest heavily on instruction and practice (Gardner, Torff, & Hatch, 1996; Olson, 1994; R. Watson, 1996). So in conclusion you will always have those that will say we still come from monkeys and those are the facts. I still do not believe that never will. Then there will be those that say that its nature that we are the way we are. I believe that nature is apart , but mostly nurture started in the beginning of life’s creation from the seed to the implantation thru adult hood.

American Romanticism essays

American Romanticism essays The literary movement known as American Romanticism can be traced back to August 31, 1837, when Waldo Emerson addressed the Phi Beta Kappa Society at Harvard College. His words became known as dazzling spell of creative energy that produced some of the most esteemed works of all time: Melvilles Moby Dick, Nathaniel Hawthornes The Scarlet Letter, and Walt Whitmans Leaves of Grass. Herman Melville, Nathaniel Hawthorne, Ralph Emerson, Whitman, and Henry David Thoreau define American Romanticism through transcendentalism, Nature, and the individual in American Romanticism. American Romantics were undoubtedly influenced by the dramatic political and social changes taking place in the early nineteenth century. The literature of American Romanticism is considered the first illustration of American literary genius. American Romanticism is expressed in a belief of self-reliance, and being humanistic. Writers associated with the romantic period matured and worked in a constantly growing nation whose conflicts where internal. The chief characteristics of the American Romantic Movement are vitality and spring time freshness. One must remember that during this movement another American spring was taking place; F.O. Matthiessen notably put it, as an American Renaissance. According to McDowell, the romantic writers sought self-reliance as individuals an as members of a newly independent nation. We will walk with our own feet; we will work with our own hands; we will speak with our own minds. In these words Ralph Waldo Emerson gave voice to the persuasive self reliance of the Romantic Generation. Emerson, Thoreau, Hawthorne, Melville and Whitman are unified by a common interest in the problems of humanity. These writers sought to explain the world by gaining a better understanding of man hims elf. Transcendentalism was a religious and intellectual movement that was a revolt ...

Important Dangers of Ordering a Fake High School Diploma

Important Dangers of Ordering a Fake High School Diploma SAT / ACT Prep Online Guides and Tips Fake high school diplomas are definitely out there. Whether you're thinking about purchasing one or doing your utmost to avoid ending up with just such a phony document, pause a moment and read this article. We'll cover reasons why a person might get a fake diploma, whether it's legal to get one, and how to make sure any document you obtain is the real deal, not a fake. Why Do People Get Fake High School Diplomas? There are a few reasons a person might look into getting a fake diploma. Some reasons are perfectly innocent, and some are more devious. However, even the supposedly innocent reasons have a somewhat fishy feeling to them- it seems very odd, for instance, that someone would invest a few hundred dollars in a very realistic-looking replica diploma intended only as a practical joke prop. Dishonest Reasons Dishonest reasons include submitting a fake high school diploma to convince a school or potential employer that you have credentials you never earned. This is the primary reason you'd need such an exactly convincing version of of diploma. It's hard to imagine why you would need to dupe people so entirely unless you honestly wanted them to believe that the document was official. Practical Reasons Many sites offering fake diplomas point out that high school diplomas are relatively likely to get lost and relatively difficult to replace. (If you're in this boat, read our guide to replacing a missing diploma.) The idea is, then, that a substitute might be a nice thing to have and to hand down to future generations. There's some logic to this argument, and yet it seems odd to hand down a fake diploma; I struggle to understand why future generations would be so attached to a stand-in document in place of simply knowing the true story of how Grandpa Bill lost his diploma from such-and-such a high school. Just-for-Fun Reasons There are all sorts of practical jokes a person could play with a fake diploma- not to mention straight-up teasing. One online figure mentioned getting a fake diploma for his dog. The question, then, becomes why you would need a document of such high (deceptive) quality; does Fido really need a seal produced with the precise embossing style that colleges use? I say no. He's sad because his diploma isn't 100% realistic. What Can You Do With a Fake High School Diploma? High school diplomas serve as a way to prove to the world that you completed your high school education with passing grades. Most of the time, you're trying to satisfy a college or an employer about your educational background; schools and businesses want to know that you have the level of education they require of their students or employees. This is where we circle back to the dishonest reasons for getting a fake diploma listed above; with a phony document, a person may be able to garner an acceptance to a college or business that would not otherwise have been offered. The story typically doesn't conclude with a happy ending, though, as we will see in the following section. What Can Happen If You Get a Fake Diploma? For one thing, it's extremely likely that you'll be discovered. In most cases, a simple phone call from the college or business to the school from which you allegedly graduated is enough to undermine your plans. Plus, organizations like schools and background check companies keep tabs on illegitimate diploma operations, updating their databases frequently. Discovery means loss of any position you may have gained with the aid of your fake diploma- at best. It can mean prosecution and conviction at worst. Are Fake Diplomas Legal or Illegal? Fake diplomas occupy a legal gray area. Laws are not stringent on this particular issue, and the exact strictness of laws varies somewhat by state. The actual production or ownership of a fake diploma is apparently not illegal if it's not technically a forgery of an actual document (for example, a replica of a Harvard diploma). Using a fake diploma to gain goods or a position you would otherwise not have access to is considered fraud, however, and can be legally prosecuted. Plus, if you're performing services you're not qualified to perform under the cover of your fake diploma, that's a big legal problem- especially if anyone suffers harm as a result. GUILTY. How to Get a Legitimate High School Diploma First and foremost, getting a high school diploma requires time and work. There's no way to get a valid diploma without completing a number of graduation requirements. There are several options for students wishing to put in the necessary work to get a high school diploma. You can, of course, attend a traditional high school. Your local school district is always a great place to start exploring that option. There's also night school, which usually intended for students who need to make up a few credits, not those wishing to start and finish their high school careers there. There are alternative high schools, too, which are structurally like your average high school but have their totally non-traditional methods. There's also the online option. Online high schools are becoming more popular these days; they basically entail getting curriculum from an online source and turning assignments in remotely. Typically, there are lectures or discussions to attend via chat or video conference. In some cases, you may want to think about the GED, which is primarily intended for students no longer enrolled in high school who have not earned their high school diplomas, though there are other circumstances where the GED might make the best sense. You can learn more about the GED and how to get a GED online through other articles on our blog. Don't you mostly just want to wear that funny hat, though? How to Make Sure the Diploma You're Getting Is Real If you're thinking of buying a diploma online, you're most likely more interested in the online mode of schooling, so these tips will focus primarily on identifying legitimate online institutions. Traits of a Legitimate Online High School Online high schools need accreditation, unless they happen to be run by a specific school district or through the state. This is a hugely important quality to check up on; accreditation is absolutely essential. You can check with your state's department of education or attorney general to see if an online program is accredited or otherwise approved. Also check out our own article explaining accredited online programs. While reviews are not 100% reliable, do check what reviewers have to say. Also, look up the online program you're considering with the Better Business Bureau. A legitimate online high school should have reasonable reviews; not everyone may be in love with the school, but if there are a lot of accusations of illegitimacy, it's something to be concerned about. Call a well-respected college and see if they would accept a diploma from the program you're looking at. If they would, that's a good sign you're on the right path; if they wouldn't, keep searching. Warning Signs of a Fake Online High School Fake online schools often charge a flat fee for a degree program, rather than charging by class or credit. Fake online schools frequently charge for the diploma itself, in addition to or instead of classes. Fake online schools may entail little or no coursework and promise little to no interaction with teachers. Some promise degrees based solely off of life experience with no classes required. Fake online schools may promise you a degree in a very short amount of time- months, weeks, or just days. The address (not just the mailing address, but the actual address of the school) may be shown as a P.O. Box rather than a physical location. The name of the school may be a knock-off of a legitimate institution. Also, some schools will maintain a cheap-looking website full of typos as well as a well-groomed and professional website, just so that you'll assume the well-groomed website must be legitimate. Look at this beautiful website! How could it possibly be unreliable? Conclusion The moral of the story here is that fake high school diplomas are, overall, not good things. They may be technically legal in some cases, and some people use them for innocent reasons, but mostly they're fraudulent and put to fraudulent use. There are ways to make sure that any program you're enrolling in is the real deal, so make sure you do your homework. Don't get stuck with a fake high school diploma: it's not worth it. What's Next?

In the development of the GUI to suit the requirements of the organization, a website with the ability to host email or live interaction between customers and sales or order processing personnel (Martin, 2006). The project manager in this case is hired on merits and experience and, therefore, his attention is divided as other projects are underway. While the project manager is expected to dedicate full attention to the tasks of this project, other members are likely to have conflicts with the idea of him running other businesses. This creates the illusion that the time allocation to tasks would involve distributing management duties to supervisor and the project analyst. Other conflicts that would be foreseeable include the project manager’s interaction with other stakeholders such as the supervisor. The supervisor is likely to feel like a project analysis is not required as he does the daily analysis and control of tasks. Finally, the sponsor is likely to dispute budget changes in case initial estimation does not meet the project goals while the programmer is tasked with code writing tasks as hourly compensation in this case may not reflect the skills needed and the magnitude of wo rk done.

Analysis of the fashion industry, - Assignment Example Fashion weeks held in the US brings in huge amount of money into the country’s reserve. On the other hand, the UK fashion industry is worth  £26 billion (Pithers, 2014). Even in the UK, this industry accounts for high number of jobs. Report states that during the London Fashion Week, more than  £100 million of orders are placed. In fashion industry, the market is segmented according to brands, which is generally concerned with creativity involved in the product design and another as per market, which again is determined by price of the product that the consumer is willing to pay. The clothing that are made in factory setting and not by hand are referred as ready-to-wear (RTW). They are also sold in the market in standard sizes (D’Aveni, 2010). These cloths are manufactured so that consumers can wear them without excessive alteration owing to the standard sizes. On the other hand, diffusion line is created by high-end fashion brands or fashion designers. These are secondary merchandises, which are available in the market at lower prices. This helps in increasing sales volume as the customer base becomes wider with lowering of the price. By leveraging desirability of the premium ranges, designers successfully tap the market through a halo effect (D’Aveni, 2010). In case of RTW clothes, the buyers’ needs are taken care of as sizes offered are standardised in nature and fit properly to majority of individuals. These clothes hardly require any alteration, which means the product is available to consumers at the desired time. Generally, this is followed by all fashion brands at present. The diffusion, on the contrary, is to increase the consumer base as brands start a secondary merchandise line, which is sold at lower prices than the primary one. There are takers for fashionable merchandises if available at affordable price. The brands are aware of the same, which is why they have taken the path of
