Hypothesis: I can successfully add vectors.
Introduction: A vector is a quantity that has magnitude (speed, force, and/or length) and direction. For example, if a person is traveling East at 60 mph, then s/he is traveling in the direction East and at a magnitude of 60 mph. A scalar is a quantity with only a magnitude. Common scalars include currency, mass, time, and acceleration. It wouldn’t make sense to say the sweater costs $38.00 southwest, so we leave off the direction. The magnitude symbol ( ), an arrow, can express direction by its angle on a coordinate plane and its length, which is usually offered. In this lab, I also use the directional measurement unit of Azimuth (Az), which is conducted by starting at North and rotating clockwise to the desired angle, most probably the angle of the vector. Adding vectors, either two positive, two negative, or one of each is done most easily by resolving, or finding each vectors’ (A, B,C,…) x and y components. Here is an example of how to resolve then add vectors:
Procedure: See lab book.

Conclusion: I successfully added three out of four vectors with a percent error of 12% or less, in which the acceptable percent error was 20% or less.
Analysis: Friction between the string and the pulley can have an effect on the lab because it makes the forces unnaturally low. To solve this problem, nullify friction by vibrating the force table. Another source of error may come when someone is putting the weights on the hooks of the pulleys and neglects to add the 50 grams of the hooks to their total force pulling on that particular string.
There were no significant error factors that may have affected the arrangement of the lab experiment. Everything went smoothly with relative ease.
Alexander Hamilton remains to be one of America’s most important people. Not only was he the first secretary of the treasury of the United States, he also was one of America’s founding fathers. Hamilton believed that a strong central government should rest on a solid financial foundation. The creation of the first national bank was to support this idea. He also served in the American army under George Washington. Hamilton also had established good relations with the British which resulted in foreign trade. “He conceived and started “The Federalist” and wrote most of those famous essays which riveted the attention of the country, furnished the weapons of argument and exposition to those who "thought continentally" in all the states, and did more than any thing else toward the adoption of the constitution.”(virtualology, paragraph 20) Hamilton created a system of tariffs which was believed to help relieve national and state debts. He then became the leader of the federalist party. Alexander Hamilton had many accomplishments in his life as a result of many various factors. But the most important trait that Hamilton possessed was his ambition

Du Bois’s short story “The Souls of Black Folk” that addresses discrimination, veils, and double-concisions and its effect on the African-American identity. To combat the modern day issue of discrimination black communities have created a movement. The movement is called “Black Live Matter. This movement campaigns against violence and systemic racism toward black people. BLM commonly protests, police violence against black people and broader issues of racial profiling, and racial inequality in the United States criminal justice system”
Powell encourage the students to always avoid the messages of hatred. He said that the free speech should inspired peace and proper information. He emphasizes on two events. “I was at the inauguration President Mandela in South Africa” (505). Where people instead hated begging to reconciled each other by exchanging spots. Where the Jailer became liberator (Dekler), and the prisoner became president (Mandela). The prisoner never had a grudge(Mandela), and he invited his three jail keepers to his ceremony. He used his spot to work with them to create a new way to avoid apartheid. Also, Powell mention about Prime Minister Rabing and PLO Chairman Arafat sing an agreement for peace and avoiding hatred and violence for several years. Powell highlights that they should behave right in order to create a peaceful society like those two historical events. He encourages the students to leave the past behind and try to not make those mistakes again. Powell seems lively trying to capture his thoughts about just what
As years went by Alexander career turned down the road of law and he passed the bar. He set up his practice in New York. His first clients was the loyalist. Who was the loyalist? American colonists who remained loyal to the British Empire and the British monarchy during the American Revolutionary War (dictionary.com). Hamilton was a New York delegate and in 1787 the Philadelphia delegate wanted to sit and talk about the Articles of Confederation, which was very weak at the time. Alexander Hamilton help write with a few other people about 51 out of 85 essays under the collective title the Federalist. Around this time Hamilton had got re-elected for the Continental Congress. Then about 1789 things had started to change with the government and he then became the Secretary of Treasury. When he began to be the Secretary of Treasury things started to change for the good and he made a report to shape the future of the country. He created an establishment for a national bank that would help national debt and war debt. A few years later he resigned because he wasn’t making enough making and went back to working with the law practice. Also he was working with Thomas Jefferson who was running against Aaron Burr for
Alexander Hamilton played many important roles in creating the new republic and one was that he was the Founding Father that helped ensure the ratification of the United States Constitution and established America’s new financial system. He was the first secretary of the treasury, among other things such as being a lawyer, member of the Continental Congress, and an author for the Federalist Papers. Hamilton’s career in helping to build the newly improved nation started when he helped lead alongside George Washington during the Revolutionary War. Hamilton is significant today because he is known as the politician that helped shape the U.S. economic system and a new way of governing the nation.
He wrote the charter for and was also an assisting founder of the Bank of New York, one of the first banks established in the United States under independence. One of his more notable ventures was his undying pursuit to ratify a new Constitution. He represented New York at the first Constitutional Convention in 1787. During the convention two main plans were proposed for government, the Virginia Plan and the New Jersey Plan. The Virginia Plan included a bicameral legislature along with an executive and judiciary that would be chosen by the national legislature. The New Jersey Plan called for a system comprised of a one-house legislature giving each state one vote. It gave Congress the power to raise revenue and established a Supreme Court with judges that were appointed for a life term. However when Hamilton attended the convention he went on to propose his own plan. He actually supported a system that was modeled similarly to the British. During the convention he advocated for his idea of a new form of government. Part of this plan included electing a leader who was given the power to govern as the president, two houses of Congress with elected representatives, a Judiciary comprised of 12 judges, and a governor who was elected as well. In his plan he stated that these positions would be served “during good behavior” meaning the elected term had no limit. So essentially governors, judges, and senators could serve until they died or until they were forcibly removed from office. The idea was not pleasing to many of his opponents at the convention because it sounded just as tyrannical as the system they had just fought so hard in a bloody war to escape. The existing Articles of Confederation contained many defects. Hamilton saw this and knew it was time to replace it with something new and improved. Even though he did not favor the final
General Colin Powell did the Commencement speech at Howard University on May 25, 1994. He did the speech after a cloud of controversy had happen at the university. A racist Black Muslim made a speech at Howard University. Howard policy is that anybody can express his or her freedom of speech on there campus. As you can figure out, the white community did not think of that very well. Connie Chung did a report saying that Howard University was a racist institution. All of this pressure was coming down at once. Howard said that they did not agree with the Black Muslims beliefs but will let them speak and express their opinions.
Gustav Klimt (GUUS-tahf klimt), perhaps best known for his controversial style, came from humble beginnings and was trained in classical style. After years of serving as an architectural painter of murals throughout Vienna, he was criticized for his overtly erotic style. This criticism served as a turning point in his career. He then revised his own sense of artistic value that ultimately led to his fall from the conservative academic art world to self discovery with an inventive and versatile style that is untouched to this day.
One possible source of experimental error could be not having a solid measurement of magnesium hydroxide nor citric acid. This is because we were told to measure out between 5.6g-5.8g for magnesium hydroxide and 14g-21g for citric acid. If accuracy measures how closely a measured value is to the accepted value and or true value, then accuracy may not have been an aspect that was achieved in this lab. Therefore, not having a solid precise measurement and accurate measurement was another source of experimental error.
Possible sources of error in this experiment include the inaccuracy of measurements, as correct measurements are vital for the experiment.
The formal and visual elements most utilized, recognizable, and original in Pablo Picasso’s Self-Portrait 1907 are line, texture, time, and color. As far as principals of design go, emphasis on proportion and scale of certain features makes them stand out, thus enhancing the expression of his face. I chose this artwork because the simplicity of the painting, especially the bold use of line, is appealing to the eye and looks like something I’d draw.
The fundamental duty of an external financial auditor is to form and express an opinion on whether the reporting entity’s financial statements are prepared in accordance with the relevant financial reporting framework. In discharging this duty, the auditor must exercise “reasonable skill, care and caution” (Lopes, J. in Kingston Cotton Mill Co 1896) as reflected in current legal and professional requirements.
