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.

When does the Total mechanical energy remain constant?
Occam's [or Ockham's] razor (William of Occam [or Ockham]; c. 1340): The recommendation that the simpler a theory is, the better. If two of the theories predict phenomena to t
A charge is said to be in equilibrium, if total force performing on it is zero. A operation of charges is said to be in equilibrium if every charge is independently is equilibrium.
Frequency The number of vibration done per second by an oscillation body is known its frequency. It is denoted by V. The S.I unit is Hz. V=1/T
