Introduction The natural source of both plasma and electromagnetic radiation (EMR) is the sun. There are various similarities such as the presence of electric and magnetic field in both EMR and plasma. Both transport contain energy and are ubiquitous in the universe. However‚ there are large differences between EMR and plasma. Differences between EMR and plasma EMR is energy that propagates through a medium in the form of EM waves. It has an electric and magnetic field which oscillate in

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

DE LA SALLE UNIVERSITY DASMARINAS Dasmarinas City‚ Cavite OBSERVING THE ELECTRICAL ACTIVITY OF THE HEART USING ELECTROCARDIOGRAM Villar‚ Samantha Belle B. Ylade‚ Kristianne Joy G. Perillo‚ Jeanne 18 March 2014 ABSTRACT In this activity‚ the electrical activity of the heart was examined using the Electrocardiogram (ECG/EKG). Proper handling was performed by removing the metals present in the body and by cleaning the surfaces of the skin‚ to avoid the disruption of signal of the machine. Assessment

Aircraft Systems and the Importance of Pilot Training The operation and maintaining of an aircraft comes with many responsibilities and obligations. This is especially true when running a scheduled airline operating under 14 C.F.R. Part 121. When under these rules‚ profit margins can be very thin and a manager must be able to lead the airline through some very difficult economic circumstances. Many of these operating procedures can be streamlined through proper pilot training and proper utilization
