PHY 114: General Physics Laboratory Lab 1: Absorption of Nuclear Radiation 09/04/13 Abstract Nuclear physics was practiced to find the value of tau. After 8 trials of using a G-M counter and 8 different mass thicknesses of polyethylene‚ a graph was formed and tau was calculated to be 0.1931 cm^2/g‚ an error of 3.57% from the accepted value of 0.2 cm^2/g. Experiment was also used as an intro to using basic lab equipment‚ computer programs and calculating errors. With many different

A very (very) long time ago‚ Machiavelli asked us‚ "do the ends justify the means?" That statement (or question) can be used to assess nearly any action. So‚ was it morally valid for the United States to drop the atomic bombs on Japan in 1945? It was a quick way to end a war‚ and it saved the lives of soldiers on both sides. Also‚ it taught us to fear nuclear power‚ as the first thing it was used for was to destroy (obliterate) two cities‚ and to kill over 200‚000 people. Next‚ it helped to spped

Density of Metals Lab 1. Purpose The purpose of this lab was answered in 4 questions‚ and their answers are here shown. The density of the metals we used were 5g/cm3. The density of a metal piece does not depend on its size‚ it depends on the total mass and total volume. The most accurate way of determining density is dividing mass by volume. You can’t identify metals by their density. It can help you narrow the options down‚ but you can’t identify a metal by using only its density. 2. Question

Albert Einstein & E=Mc2 Floris K Albert Einstein was born in Germany on March 14‚ 1879.He was a theoretical physicist and his energy formula‚ E= MC2‚ made him a world famous mathematician. Before Hitler came to power in Germany‚ Einstein worked as a University professor in Berlin. He was visiting the United States when Hitler took power‚ and decided to stay in the US‚ becoming a citizen in 1940. During the war he worked on the Manhattan Project‚ which was a project that produced the first atomic

In his article‚ “Why Fukushima made me stop worrying and love nuclear power”‚ Monbiot (2012) he uses inductive form approach on his fist key argument to support his main claim which stated that there is no ideal solution in the energy technologies but the impacts created by nuclear is smaller than other solutions. He supported his key argument with two observations. First observation is Fukushima nuclear disaster shows that there were no fatal cases caused by exposure to radioactive rays although

Is It So Safe to Use Nuclear Energy? The fragile environment of our planet is now under threat. Carbon fuels such as coal and oil are running out and their emissions are destroying the ecosystem. To prevent the harmful effect on the environment‚ Dr Symonds discussed his view that nuclear power is the best affordable way to protect the nature of the Earth. Although the facts introduced at the conference were quite persuasive‚ there are some points to argue. There was a statement in which Dr Symonds

Throughout many scientific advances in the centuries of science‚ most citizens often forget the contributors of these discoveries and advancements in modern-day technology. One of the many contributors that are responsible for changing our world through science is James Chadwick. James Chadwick was born on October 20th‚ 1891 and started his journey in the science world in 1908‚ Experiments done in Europe by Frederic and Irene Joliot Curie had caught his attention‚ leading him toward the study of

If someone were to ask you what is radium or who discovered radium‚ would you be able to answer correctly? You may say that radium is not vital in today’s society or that you could care less about radium‚ but what if you were informed that fifteen percent of the world’s electricity is produced with the help of radium and nuclear power plants. Would you change your mind about the importance of radium? Not many people know but‚ radium is also frequently used in the medical field specially to run

About Radiation: Radiation is an energy that is transmitted in the form of waves or tiny particles. These are electromagnetic waves‚ which are classified as ’ionizing radiation’ and ’non ionizing radiation’. Electromagnetic radiation is when an object gives out electromagnetic radiation. For example when you on a torch light‚ the light is an example of radiation. Ionising radiation has more energy than non ionising radiation. Therefore it is enough to cause chemical changes by breaking chemical

The United States is the worlds largest producer of nuclear power‚ accounting for more than 30 percent of the worldwide nuclear generation of electricity. Nuclear power is also among the verge of the most expensive‚ construction on a new power plant in Georgia skyrocketed past the projected expenses by $737 million to nearly $7 billion. In 2012 the approval of the new power plants in Georgia and South Carolina were among the first approved in over 30 years. While these approvals were a major setback
