Experiment 4 Measurement of e by Thomson’s bar magnet method. m Apparatus: Cathode ray tube (CRT) with power supply unit‚ one pair of bar magnets‚ high resistance voltmeter‚ magnetometer‚ stopwatch. Purpose of experiment: e To measure the specific charge‚ i.e. charge to mass ratio ‚ of an electron using m Thomson’s bar magnet method. Basic methodology: Electrons in a CRT are deflected in the vertical direction by applying a potential between the vertical deflection plates of the CRT.

chamber by exhaust gases. Fly ash is the fine powder formed from the mineral matter in coal‚ consisting of the noncombustible matter in coal plus a small amount of carbon that remains from incomplete combustion. Fly ash is generally captured by electrostatic precipitators or other particle filtration equipments before the flue gases reach the chimneys. Flotation Flotation is one of the many methods in mineral separation. It could be used for separation of phases for instance to remove solid particles

needed to move two surfaces past one another if they are rough than if they are smooth. However‚ friction decreases with smoothness only to a degree; friction actually increases between two extremely smooth surfaces because of increased attractive electrostatic forces between their atoms. Friction does not depend on the amount of surface area in contact between the moving bodies or (within certain limits) on the relative speed of the bodies. It does‚ however‚ depend on the magnitude of the forces holding

Plasma Complexity! Plasma is said to a substance similar to gas in which a certain portion of the particles are ionized. The basic premise is that heating a gas dissociates its molecular bonds‚ rendering it into its constituent atoms. Further heating leads ionization‚ turning it into plasma: containing charged particles‚ positive ions and negative electrons. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic

Global positioning system (GPS) The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites that orbit the earth at approximately 12‚000 miles above surface and make two complete orbits every 24 hours. Placed into orbit by the U.S. Department of Defense the GPS was originally intended for military applications‚ but in the 1980s‚ the government made the system available for civilian use. GPS works in any weather conditions‚ anywhere in the world
