GCSE Physics Coursework - Resistance of a Wire Coursework Introduction (Theory) In this piece of Coursework I am going to investigate the resistance in a piece of wire. Resistance is the force that slows down the flow of electrons; this can be due to electrons colliding. The total length of the wires will affect the amount of resistance. The longer the wire‚ the more resistance that there will be. This is also true for thickness of wire; the thinner the wire is the more resistance. Resistance

Why Oxygen is Important Oxygen plays a vital role in the treatment of patients. Oxygen is the molecule that helps the cells in our body produce ATP through a process known as cellular respiration. Also it is the number one drug of choice for the American heart association. Finally it is a priority according to the universal care protocols in the protocol book given to flight medics in USAAAD at Fort Polk. In short Oxygen is important for the medics to use. To start off with oxygen helps sustain

Accounting systems can provide enormous amounts of information‚ including full profit statements‚ balance sheets and details of outstanding debtors‚ creditors and stock-holding levels. Sometimes they produce so much information that owner-managers cannot cope and prefer to ignore them. In fact‚ most small firms can be controlled by monitoring‚ on a timely basis‚ just six pieces of information that tell the owner-manager different‚ but vital‚ information on the performance of the business. These are

Coasha Patton 1st February‚2013 History What factors contributed to the social unrest of the 1930’s and the 1940’s? When citizens are not satisfied ‚ something is lead to happen ‚ this is called an unrest. The Bahamas between the years 1930 to 1940‚ social unrest came about. That Bahamians were fed up with the categorization or separation of society that they were placed in‚ in their own country. The Bahamas always experienced social unrest but it was during these years that its strength increased

Tyrian Reed Chemistry 1st Period The History Of Oxygen Oxygen is a chemical element with symbol O and atomic number 8. One of the first known experiments on the relationship between combustion and air was conducted by the 2nd century BCE Greek writer on mechanics‚ Philo of Byzantium. Many centuries later Leonardo da Vinci built on Philo’s work by observing that a portion of air is consumed during combustion and respiration. In the late 17th century‚ Robert Boyle proved that air is necessary

Essay 1 An individual’s work achievement can be best predicted by measuring their intelligence. Discuss. In modern life‚ the motive to success in career has been researched in order to benefit both individual and organisation. The term “intelligence” has been acknowledged over the world as a common way to compare between individual people. Majority believe that succeed of every people can be best measured in that way. However‚ after many year of using that‚ some people argue intelligence

I was testing different temperatures and how it affects the time catalase takes for it to break down peroxide. The problem that i was investigating is how does temperature affect the time it takes for catalase to break down peroxide. My independent variable for this lab was the temperature of the solution the enzyme is in. My dependent variable in this experiment was rate of reaction or the amount of time it takes to sink and rise. My hypothesis is that if the temperature is higher than 37℃‚ then

GCSE Physics Coursework - Resistance of a Wire Coursework Resistance of a Wire Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Electricity is conducted through a conductor‚ in this case wire‚ by means of free electrons. The number of free electrons depends on the material and more free electrons means a better conductor‚ i.e. it has less resistance. For example‚ gold has more free electrons than

Biochemical oxygen demand ( and COD) It is a measure of the amount of oxygen required by bacteria‚ algae‚ sediments and chemicals over a set period of time. BOD is of importance in aquaculture because microbial degradation of organic matter is a major sink for dissolved oxygen‚ a highly important parameter for

| Ibuprofen Ibuprofen is a well-known drug that possesses analgesic (pain-relieving) and antipyretic (fever-reducing) properties. It is particularly known for its use in pain relief from arthritis. Ibuprofen was discovered by Dr. Stewart Adams and his colleagues in the United Kingdom in the 1950s‚ patented in 1961‚ and first made available in 1969. It became available in the United States in 1974. Ibuprofen tablets are sold under the trade names Advil and Motrin. (K. Adrjanowicz) This pharmaceutical
