Temporary Works to Superstructures (Slabs) Essay

Temporary Works to Superstructures (Slabs) - Essay Example The braking system applies friction on the tire during braking and as a result, the kinetic energy is converted to heat and sometimes noise. However, the hybrid car is so energy conservative such that it uses its energy with minimal losses. The energy is converted into electrical energy by the motor installed on the car and is stored in the battery. Thus, in place of the normal braking system of friction, the car uses the electric motor. The motor runs in the opposite direction to the tires, and in so doing acts as generator, converting the lost energy into electrical energy for storage in the battery. The earth’s potential energy The earth is another system that has got very much energy pent up within its interior. This energy manifests itself in various ways, but the most common is the earth tremors and earthquakes that are experienced. This energy moves in the earth’s interior as waves referred to as seismic waves. These waves cause the movement of the earth plates. Once these waves meet and slip over each other, the pent up energy is released promptly and is propagated to the earths surface inform of seismic waves. There are of two main types, the primary waves also called longitudinal waves and the secondary waves also called transverse. The primary waves travel faster than the secondary waves but the secondary are stronger than the primary waves. If this energy is not anticipated and happens to be very high, it causes catastrophic effects on the earth. Structures are brought down and others destroyed for good. Means of harnessing this energy have not been discovered. Electric field energy The field of electric energy has really been exploited. The law enforcement agencies have also embraced this technology and developed a very beautiful and efficient gun. These guns use battery and an inbuilt circuit to produce charges. These are connected to electrodes which when the electric field created encounters the body, disrupt the nerves electrical signals which control the body muscles, making the muscles non-active and hence the criminal is subdued easily. The charge used to produce these electrical fields is regulated such that it does not cause any harm to the criminal. Another fine advancement is the discovery of the electric fish. Fish tat produce electric fields actively are known as electrogenic fish. They achieve the separation of charge by having an electric organ. The electroplates are disk like and hence once the brain launches the message, the plates become charged by a chemical progression which is just the same as that of the nerves functioning. There are many fish that are electric but the most common are the electric eel and catfish. These fish use these electric fields for catching and subduing their prey. The fish that have strong electric fields such as the eel, whose electric field makes up to fifty percent of its body, can kill a prey instantaneously as they touch it with the electrodes. They also use the se fields for locating prey or other organisms and for communicating with each other. Some fish such as the elephant nose have weak electric fields and hence they use them for communicating only. Their electric charge is as good as that contained in the batteries. Lightening energy Lightening, usually observed as a flash of light on the sky is another form
