Graphical Analysis Essay Example for Free

Graphical Analysis Essay This part of the experiment looked at a pendulum to see the relationship between the length of string and the time it took to do ten full oscillations. Unlike the rubber band experiment the results produced a curve. The best-fit curve was produced from a power regression using the Graphical Analysis software and the Ti-83 plus calculator to cut down on systematic error. This fit was much better than the linear regression because more points lie on the curve and it also supports what the textbook says. In both experiments the possibility of errors are a concern; a concern that must not be forgotten. Systematic error is caused by the mis-collection of data or an improper model. One type of error that is always found is random error. It is the combination of errors that are important and calculated differently depending on the circumstances. Relative error gives more meaning to the importance of a random error. It is much easier to see the influence of a particular error when it is compared to the whole to make a percentage of error. The general function to determine error is a derivative of the function multiplied by the error. For example the error formula of y = x5 then the error formula is 54 ? x. The error formula for y = VX is (1 / (2VX)) ? X. Shortcuts can be used when determining the relative error of z when z = xy by adding the relative errors of x and y (? z = ? x/x + ? y/y). This can be done because of the following proof: ? z = x? y + y? x and z = xy then ? z/z = (x? y + y? x) / xy. The shortcut ? z/z = ? x/x + ? y/y is the same equation when a common denominator is calculated as xy. The same holds true for division z = x/y with the same result being ? z/z = ? x/x + ? y/y. Traditionally the equation would initially look like ? z/z = ((x? y + y? x)/y2) / (x/y), which is also the same as saying ((x? y + y? x) / y2) X (y/x). After the y/x is multiplied through then the same equation as the former is produced which is ? z/z = (x? y + y? x) / xy therefore proving the results. Method Part D Part D of the experiment looked at the quadratic function and its unique properties. The quadratic function of y = 10 + 30t 4. 9t2 was graphed using Graphical Analysis. This function represents a ball thrown upwards at 30 m/s with gravity working against it causing a downward motion. Figure 3 shows the resulting graph. This is just a theoretical situation and does not represent data collected. Analysis Part D The graphed quadratic function helps to understand the quadratic relationship more closely. It is a very useful function in physics because it is often seen when using motion. The roots are a very important part of the function. These are the points at which the curve crosses through the horizontal axis when y = 0. To figure this out the quadratic function can be rewritten as: x = -b/2a i Vb2 4ac / 2a. The graph is helpful to quickly see where the roots are. The Graphical Analysis software allowed me to zoom into the roots closer than what figure 3 allows to be seen. Visually the roots looked to be -0. 32 and 6. 44 but with a calculator the equation was a little more accurate for the first root at -0. 317. Using the proper number of significant figures then the answers would be the same whether calculated or visually enhanced. Looking at the equation more closely shows an interesting equation within the bigger one. Before the i symbol is -b / 2a, which is the same for both roots. This is important because the quadratic equation is symmetrical and the -b / 2a equation points to the apex of the curve, like a mid-point. Another note on this point is that the point is also where the slope = 0, which is when the ball would begin falling back to the earth. Conclusion This lab looked at some of the different physical relationships that are current theories or laws. The experiments verified these relationships.

Why the Nazis and not the Communists? :: European Europe History

Why the Nazis and not the Communists? Why, by 1934, had the Nazis benefited more than the Communists from the shortcomings of the Weimar Republic? Adolf Hitler, head of the NSDAP, became Chancellor of Germany on the 30th January 1933. Following the 'legal revolution' of the following months and President Hindenburg's death on the 2nd August 1934, Hitler made himself FÃ ¼hrer and Reichskanzler. The Nazi revolution was complete and Germany was subject to a dictatorship of the extreme political right. As Ian Kershaw explains, the Weimar Republic was failing: "the survival chances of Weimar democracy might be regarded as fairly poor by the end of 1929, very low by the end of 1930, remote by the middle of 1931 and as good as zero by Spring 1932." In a period of Depression and when unity and firm government was essential, MÃ ¼ller's Grand Coalition broke up in March 1930. Logically, there were several political alternatives other than Hitler and the Nazis. There could have been a return to parliamentary Party politics. There were some signs to show that democracy may have been revived. During the continuous utilisation of Article 48 to govern, the Reichstag gave their vote of no confidence in challenging the executive use of it. Also, a section of the public appeared to still support the Republic; the Centre Party and SPD continued to have steady support until 1932. However, it seems that any chances of democracy were ruled out. The political Parties were still inclined to pursue their own political interests when a united, broad and moderate front was needed. Two moderate Parties even defected to Hitler after the offensive from the right and Hindenburg made little effort to restore the influence of the Reichstag. Alternatively, Germany could have become a presidential dictatorship backed by the army as von Schleicher or von Papen would have preferred. In order to do this, the authoritarian regime would have had to adapt slightly from what it was in 1932. The long-term use of Article 48, the emergency decree, would have been impractical and impossible. Perhaps the conservative elites were looking to Hitler for a new identity as they couldn't return to the days of the Second Reich as well as thinking they could control his power. A military regime would have meant that there was no dominance from the extreme right or left of politics. Judging by the situation of Germany at that time, it was quite possible that this may have resulted in civil war.

The Autobiography of Benjamin Franklin-Response Paper

Running head: PATH TO AUTO-IMPROVEMENT 1 The Autobiography of Benjamin Franklin: The Path to the Auto-improvement Luis A. Cruz Prof. Jerry Wallace HIST 1301 University of Texas at El Paso PATH TO AUTO-IMPROVEMENT 2 The Autobiography of Benjamin Franklin: The Path to the Auto-improvement The main reason that Franklin had to write his autobiography was to show how to live the life in a better way, at least in Franklin? experience. Franklin added two letters that eventually convinced him to finish his project of writing his autobiography. The letters (one from Mr. Able James and the other from Mr. Benjamin Vaughan) said to Franklin about the importance that had others would know about his life. Actually this book was not destined to talk about his role during the American Revolution. In fact, this book is about a way to get a life of excellence. During his autobiography Franklin remarked the facts that he thought more relevant for the auto-betterment.The main factors that I like were: the importance of reading, the education that Franklin? s father gave him and the accepting mistakes. During four parts of the autobiography, Franklin talked about how the books make him better. Franklin? s love for the books during his childhood was very important for his success. It is easier to acquire knowledge from books if you like reading than if it is just done as a task. His abilities for reading grew enough to develop his writing. At the time Franklin had developed reading (to gain knowledge) and writing (to transmit it) he is converted in a respectable man.In the most part of his life, due his knowledge, Franklin was very helpful in the development of the town where he lived. Also, with reading, Franklin reshaped his life style. For example, just consuming vegetables (sometimes ate fish), or just drinking water and nothing of beer although others laughed of it. Maybe getting a healthy life helped to the long life of Franklin. PATH TO AUTO-IMPROVEMENT 3 Next, Franklin? s father was too important in his development as person.I think the most important fact was when Franklin stole some quarry stones for a wharf. But when his father took notice of this, he taught to Franklin that when something bad is done to accomplish anything, then this does not worth it. Also, Franklin during his childhood and youth notice the importance of knowledge. Franklin saw his father as a respected man due his impartiality and capacity to solve problems. This example became a model to live in society for Franklin. Finally, Franklin showed the significance of accepting mistakes.Franklin said that he committed a very big mistake when he loses contact with Miss Read. At the time he returned from England, he married with Miss Read. Franklin believed that left her in the past was a big mistake because when they are married, they became happier. Also, accepting mistakes meant for Franklin the happiness. When he took notice that he could not be perfect, then just does not live mo re under pressure to reach perfection. This did not mean leave his life style. In conclusion, I think this is a very helpful book.Actually I believed that it would be more engaged with American history, but eventually, the lessons were very interesting like the importance of reading, the thirteen virtues, or working for the community. On the other hand, I think that the book is very hard to read due the differences and useless of some words, it is necessary a dictionary. Also, the way to write an autobiography is not the better. I remembered had read The Autobiography of Malcolm X, and this had a better sequence. Although this book was not made as a history resource, it helps to know the way of life in this era.

Globalization is the process of development in politics, economy and culture all around the world. National economies becomes increasingly integrated through globalization. Although globalization brings positive effect on economy, it also affects the world in a negative way. To start with, globalization has improved interdependence of national economies. Globalization involved free trade, greater competition, and increased investment. Globalization allows companies to enter wider markets and consumers have more options of goods and services.Free trade is a trade between countries without governmental intervention. Globalization lows greater trade and competition in the market that leads to lower prices, higher economic growth and it also increases level of investment. Since companies open wider markets, they need more people to work for them. Globalization enables a larger job opportunity that leads to decreasing of unemployment. Globalization allows us to move from one to another co untry. Free movement of labor gives advantages to both sender and recipient countries.If a nation experiences high unemployment, there are large opportunities to look for jobs somewhere else. Globalization increases Gross Domestic Product (GAP) of a country. GAP is the market value of all final goods and services produced within a country in a given period of time. Production of foreign companies in a country is counted as a part of country's GAP. A massive increase in education is also result of the globalization process. However, globalization brings negative impacts on a nation. Developing countries have difficulties to compete with developed countries.Globalization drives migration. So many people with different background move in and out Of a Country. They tend to follow the foreign culture and forget their own culture, this can lead to cultural conflicts. Opening doors to international trade has increased intense competition. Local products often struggle to compete with impor ted products because imported products are usually cheaper and better. Globalization has increased standard of living. People in recent times tend to buy branded products more than local products. Thereby the local companies suffer huge losses.Globalization allows workers to move freely. Hence, it is difficult for some countries to hold onto their best skilled workers who are attracted by higher salaries in other countries. Economic bloc or trade bloc is an agreement between countries, to acclimate trade between participants. For example, The European Union (SEC)). The E has 28 members (Austria, Germany, Norway, Belgium, Greece, Poland, Bulgaria, Ireland, Portugal, Cyprus, Italy, Romania, Croatia, Latvia, Spain, Czech Republic, Lithuania, Slovenia, Denmark, Luxembourg, Slovakia, Estonia, Malta, Sweden, Finland, Netherlands, UK and France).The aim is to promote free trade between countries. Multinational Corporation also knows as transnational corporation, is a corporation that has i ts assets in several countries but managed from one country such as Coca Cola. Multinational Corporation is beneficial because it creates jobs and improves technology. Business cycle refers to the change of economic activity. Economy experiences ups and downs caused by the changes of supply and demand. The changes of economic growth in the global economy over time are known as international business cycle.In labor markets, employers compete to hire the best skilled workers, while workers compete to get the best satisfying job. In recent time, more people are moving to different countries to get a better quality of life and standard of living. High skilled workers are attracted to rich Mounties such as the United States because of the higher wages and better opportunities. Small countries often struggle to hold onto their most talented and skilled workers, who are attracted to other countries by greater rewards (Australia in the Global Economy, 2004).The globalization of labor market has been increasing, however there are still significant difficulties on working in other countries such as language, immigration restrictions, cultural factors, and incompatible educational and professional qualifications. For example, people from Mexico who move to America. 10,000 people cross the Mexican order every week. People usually move to find a job, to avoid war, to find a better quality of life or to be closer to their friends or family.Those migrants often struggle to live in rural Mexico because they have to survive with very little money; most of the population is living in poverty. The lack of resources makes they live harder to gain money. They believe by moving to America they can get a better life. Rural Mexico doesn't have minimum wage like in America; what they make in a whole day at Mexico would be few hour work in the USA. Migrants are usually fathers Of big families that have to cross the border, then end home bunches of money or return to their homes.Some of them move to America in a legal way and some with an illegal way. Those who don't have valid passport and visa are willing to cross the desert that separates Mexico and America. Many people suffer dehydration when they are crossing and the border patrol may catch them. These migrants bring impacts on both Mexico and America. The impacts on America are local businesses have benefited as they have a source of cheap labor, Mexicans are willing to do anything, and Mexicans have brought their culture and food with them that makes Mexican DOD very popular in the LISA.However, The LISA government has to spend millions of dollars for border patrols and prisons due to illegal migrants (recently it has been a concern that there may be terrorists crossing the border. ) Mexicans also cause social problems due cultural and racial issues and also many Americans feel that Mexicans are taking their jobs. On the other side, Mexico has less of economically active people; young people tend to migrate and leave the old and the very young. In the final analysis, globalization can benefit people but it can cost people too.Indonesia been terrorized recently, more jobs are provided so people become wealthier. Quality of life in Indonesia is increasing; the government now has more money to spend because people can afford to buy more expensive things. Globalization is at its peak and it is clear that globalization cannot be stopped.

Moon Palace essays

Moon Palace essays The central character in Moon Palace Marco Stanley Fogg lost his mother, when he was only a boy and he never had a father so he was raised by his uncle Victor, who also had a very positive influence on him. Marco lost his uncle, while he still were attending college and Marco changed into a careless person after his vital loss, actually the situation of his loneliness had caused a mental transformation which ended with Marco loosing his apartment. After his eviction he lived on the streets for several months and he became totally isolated from society. Marco was selling books, which he inherited from his uncle to finance his living and he was rescued from the streets by his old friend Zimmer from his university days and a young Chinese woman named Kitty Wu. After living with Zimmer, Marco gradually recovered and when he became lovers with Kitty Wu he started to see a purpose with life. Marco eventually managed to find a job as the person in charge for the blind and paralysed Thomas Effing and his main job was to write the story of Mr Effings life. Effing wanted Marco to write his obituary for him, so he began telling Marco all about his life and with these stories he relived that he was a famous painter named Julian Barker. Shortly after the completion of his obituary, Mr Effing died May 12th as he had predicted himself and Marco found Mr Effing son Solomon Barber to hand the notes over to him. Marco also found out after meeting Solomon that he was his father and Effing was his grandfather. When they went to visit Marcoss mother Emilys and his Uncle Victors graves in Chicago, Solomon accidentally fell into an open grave and broke his back. Two month after he died and Marco started walking west after getting his inherited money stolen. The moon has an important role in the book, because it is following the characters in the story. The symbol of the moon is the factor that leads the ...

Closer look at teens essays

Closer look at teens essays It is important not to overreact to isolated incidents. Young people will have problems and will learn, at their own rate, to struggle and deal with them. But it is critical for parents and helping adults to be aware of the factors that put a youth at particular risk, especially when stressful events begin to accumulate for these vulnerable individuals. A good starting point for identifying and intervening with highly troubled and depressed young people is the careful study of suicidal adolescents. Family history and biology can create a predisposition for dealing poorly with stress. These factors make a person susceptible to depression and self-destructive behavior. History of depression and/or suicide in the family Alcoholism or drug use in the family Sexual or physical abuse patterns in the family Chronic illness in oneself or family Family or individual history of psychiatric disorders such as eating disorders, schizophrenia, manic-depressive disorder, conduct disorders, delinquency Death or serious loss in the family Learning disabilities or mental/physical disabilities Absent or divorced parents; inadequate bonding in adoptive families Family conflict; poor parent/child relationships Personality traits, especially when they change dramatically, can signal serious trouble. These traits include: Impulsive behaviors, obsessions and unreal fears Aggressive and antisocial behavior Withdrawal and isolation; detachment Poor social skills resulting in feelings of humiliation, poor self-worth, blame and feeling ugly Over-achieving and extreme pressure to perform Problems with sleeping and/or eating Psychological and social events contribute to the accumulation of problems and stressors. Loss experience such as a death or sui ...

How to Write a Learning Contract and Realize Your Goals

How to Write a Learning Contract and Realize Your Goals We often know what we want, but not how to get it. Writing a learning contract with ourselves can help us create a roadmap that compares our current abilities with desired abilities and determine the best strategy for bridging the gap. In a learning contract, youll identify learning objectives, available resources, obstacles and solutions, deadlines, and measurements. How to Write a Learning Contract Determine the abilities required in your desired position. Consider conducting information interviews with someone in the job you seek  and ask questions about exactly what you need to know. Your local librarian can also help you with this.What are you going back to school to learn?What job do you want?What knowledge, skills, and abilities do you need to have in order to get the job you desire?Determine your current abilities based on prior learning and experience. Make a list of the knowledge, skills, and abilities you already have from prior school and work experience. It can be helpful to ask people who know you or have worked with you. We often overlook talents in ourselves that are easily noticed by others.Compare your two lists and make a third list of the skills you need and dont yet have. This is called gap analysis. What knowledge, skills, and abilities will you need for your dream job that you havent yet developed? This list will help you determine the appropriate school for you and the classes youll need to take. Write objectives for learning the skills you listed in Step 3. Learning objectives are very similar to SMART goals. SMART goals are:Specific (Give a detailed description.)Measurable (How will you know youve achieved it?)Achievable (Is your objective reasonable?)Results-oriented (Phrase with the end result in mind.)Time-phased (Include a deadline.) Example:Learning objective: To speak conversational Italian fluently enough before traveling to Italy on (date) that I can travel without speaking English. Identify available resources for reaching your objectives. How will you go about learning the skills on your list?Is there a local school that teaches your subjects?Are there online courses you can take?What books are available to you?Are there study groups you can join?Who will help you if you get stuck?Is there a library accessible to you?Do you have the computer technology you need?Do you have the finances you need?Create a strategy for using those resources to meet your objectives. Once you know the resources available to you, choose the ones that match the way you learn best. Know your learning style. Some people learn better in a classroom setting, and others prefer the solitary study of learning online. Choose the strategy that will be most likely to help you succeed.Identify potential obstacles. What problems might you encounter as you begin your study? Anticipating problems will help you be ready to overcome them, and you wont be thrown off course by a nasty surprise. Think of everything that might become an obstacle and write it down. Your computer could break. Your daycare arrangements could fall through. You might get sick. What if you dont get along with your teacher? What will you do if you dont understand the lessons? Your spouse or partner complains youre never available. Identify solutions to each obstacle. Decide what you will do if any of the obstacles on your list actually happen. Having a plan for potential problems frees your mind of worry and allows you to focus on your studies.Specify a deadline for meeting your objectives. Each objective may have a different deadline, depending on whats involved. Choose a date that is realistic, write it down, and work your strategy. Objectives that dont have a deadline have a tendency to go on and on forever. Work toward a specific goal with a desired end in mind.Determine how you will measure your success. How will you know if youve succeeded or not?Will you pass a test?Will you be able to perform a specific task in a certain manner?Will a particular person evaluate you and judge your competency?Review your first draft with several friends or teachers. Go back to the people you consulted in Step 2 and ask them to review your contract. You alone are responsible for whether or not you succeed, but there are l ots of people available to help you. Part of being a student is accepting what you dont know and seeking help in learning it. You might ask them if:Your objectives are realistic given your personality and study habitsThey know of other resources available to youThey can think of any other obstacles or solutionsThey have any comments or suggestions regarding your strategy Make the suggested changes and begin. Edit your learning contract based on the feedback you receive, and then begin your journey. Youve got a map drawn specifically for you and designed with your success in mind. You can do this. Tips When youre thinking of the people in your life you might be able to ask for input, consider the ones who will tell you the truth, not the ones who will tell you what you want to hear or say only nice things. Your success is at stake. You need to know the good things  and the bad. Ask the people who will be honest with you.Online forums are great places to talk with other people who share your goals. Participate by posting your questions, responding to other peoples questions, and getting to know people who are interested in the same things you are.
