Vincent Phelps Mr. Anderson English 10 December 2012 Cell Phones of Death Skeptics have been saying cell phones cause dangerous side effects. As a result‚ some people claim that when magnetic waves are sent from cell phones‚ the waves have an allergic reaction on them. Others are saying these same waves caused their cancer. However‚ I have found virtually no studies that support these claims with scientific evidence. This is the reason for my choice of policy. The policies in regards to

The Rutherford Model of the Atom 1. In 1911 Rutherford proposed the nuclear model of atomic structure. He suggested that an atom consists of a central nucleus (where most of the mass of the atom is concentrated) having a positive charge‚ surrounded by moving electrons carrying negative charge. Geiger and Marsden carried out an experiment to verify his proposal. The Geiger/Marsden a Particle Scattering Experiment 1. The apparatus is illustrated in the diagram below. | 2. The apparatus

In electricity generation‚ an electric generator is a device that converts mechanical energy to electrical energy. A generator forces electrons in the windings to flow through the external electrical circuit. It is somewhat analogous to a water pump‚ which creates a flow of water but does not create the water inside. The source of mechanical energy may be a reciprocating or turbine steam engine‚ water falling through a turbine or waterwheel‚ an internal combustion engine‚ a wind turbine‚ a hand crank

Purpose The purpose of this experiment is to test Coulomb’s Law which states that the force between two spherically symmetric charged objects is directly proportional to the product of the charges‚ and inversely proportional to the square of the distance between the centers of the two charges. In mathematical vector notation Coulomb’s Law is expressed as where Fr is the force on particle 1 due to particle 2 in Newtons‚ q is the charge on 12 1 particle 1 in Coulombs‚ q2 is the charge on particle

ELECTRICITY I. DISCOVER OF ELECTRICITY About 600 B.C.‚ Thales‚ a Greek philosopher and scientist‚ observed that a piece of amber attracted small bits of “paper” or very thin wood shavings after it was rubbed with wool. He had discovered‚ in effect‚ static electricity. William Gilbert‚ an English scientist in the sixteenth century‚ found that many other different materials could be made to act like amber. Whenever these objects were rubbed against each other‚ they were able to attract each other
