2013 Energy Lost . . . Energy Saved . . . My family and many others have been tricked by the media. We have probably all – at one time or another – been succored into to buying an appliance or electrical device based off whether it’s the cheapest one. By doing this you have been fooled by society! Your purchase should not be based on price‚ but by how much energy the appliance consumes. The appliance might be cheaper‚ but it mostly likely uses a considerably larger amount of energy than the

During exercise the body uses up large amounts of energy in three different ways. The ATP/CP system‚ anaerobic system and the Aerobic system all combine during periods of exercise to allow our bodies to continue exercise or playing sport. Most sports have a major system which takes up the bulk of the energy production during the activity and the timing in switching from one to another. This plays a major role in success in the playing arena. In a sport such as Australian Rules football it is important

Energy Crises Energy is considered to be life line of any economy and most vital instrument of socioeconomic development of a country. Energy is pivotal in running machinery in factories and industrial units‚ for lighting our cities and powering our vehicles etc. There has been an enormous increase in the demand of energy as a result of industrial development and population growth‚ in comparison to enhancement in energy production. Supply of energy is‚ therefore‚ far less than the actual

MINOR MEMBERS OF THE SOLAR SYSTEM ASTEROIDS Asteroids are small rocky bodies that have been likened to “flying mountains.” The largest‚ Ceres‚ is about 1000 kilometers in diameter‚ but most are only about 1 kilometer across. The smallest asteroids are assumed to be no larger than grains of sand. Most asteroids lie between the orbits of Mars and Jupiter. They have orbital periods of three to six years. Some asteroids have very eccentric orbits and travel very close to the sun‚ and a few larger

Types of Energy: Energy is the ability to do work and there are many types of energy. Mechanical Energy is the energy of motion that does the work like the wind turns a windmill. In physics‚ mechanical energy is the sum of potential energy and kinetic energy present in the components of a mechanical system. It is the energy associated with the motion and position of an object. The law of conservation of energy states that in an isolated system that is only subject to conservative forces‚ like

Atomic energy By: Hiram A. Murray III Background info The origin of the phrase atomic energy check in from the years of 1905-10. It is defined as energy released by reactions within atomic nuclei‚ as in nuclear fission or fusion. Now a days it is referred to Nuclear energy. Nuclear power uses fission (splitting atom nuclei) to produce energy. Atom nuclei is also none as the nucleus (center of the atom). Around 6% of the world’s energy and 14% of the world’s electricity is produced by nuclear

NUCLEAR ENERGY AND SAFETY Consumption of energy is increasing nowadays so nuclear energy has very importance for energy needs. Nuclear energy is produced naturally and in man-made operations under human control and it is a thriving global industry. A total of 435 nuclear power plants are operating around the world in 30 countries. Also ‚ nuclear energy has some advantages Nuclear energy has the lowest impact than fossil fuel energy on environment because nuclear plants don ’t emit

ADC0803‚ ADC0804 ® Data Sheet August 2002 8-Bit‚ Microprocessor-Compatible‚ A/D Converters FN3094.4 Features The ADC080X family are CMOS 8-Bit‚ successiveapproximation A/D converters which use a modified potentiometric ladder and are designed to operate with the 8080A control bus via three-state outputs. These converters appear to the processor as memory locations or I/O ports‚ and hence no interfacing logic is required. The differential analog voltage input has good commonmode-rejection
