Explain about the Heat Extraction?
a) A body of mass M has a temperature-independent precise heat C. If the body is heated reversibly from a temperature Ti to a temperature Tf what is the change in its entropy?
b) Two such bodies are primarily at temperatures of 100 K and 400 K. A reversible engine is used to take out heat with the hotter body as a source and the cooler body as a sink. What is the maximum quantity of heat that can be extracted in units of MC?
c) The specific heat of water is C= 402j/g k and its density is 1g/cm3 Calculate the maximum useful work that can be extracted, using as a source 103 m3 of water at 100°C and a lake of temperature 10°C as a sink.

What is the solution of Simple Harmonic Motion?
As CPH is a boson, does it has structure? Answer; a CPH is tiny energy and it is not a boson. When a CPH takes spin, then it converts to graviton.
The process of transformation of one element into another by bombarding it with high energy particles is called "Artificial transmutation". Artificial radio activity is the proc
