Advantages of Using Solar Energy - It is present everywhere. It is available in plenty. It does not cause any environmental pollution like the fossil fuels and nuclear power. Solar cells last a longer time and have low running costs. In the first half of the twentieth centu..

Formation of Our Solar System - Many scientists believe that our solar system was formed from a giant, rotating cloud of gas and dust known as the solar nebula. According to this theory, the solar nebula began to collapse because of its own gravity. Some astr..

Advantages of Using Solar Cells - It is present in abundance They have no moving parts and hence require little maintenance and work quite satisfactorily without any focusing device It does not cause any environmental pollution like the fossil fuels and nuclear power Solar ..

.A copper-constantan thermocouple is used between S 1 and S 2 .When sun's rays fall on S 1 , its temperature rises. The temperature of the junction (of the thermocouple) near S 1 increases. The galvanometer gives deflection. Now, current is passed through S 2 , so that temperature of S 2 becomes eq..
