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.
Direct Current (DC): Such a current can be getting by connecting the two ends of a conductor to the terminals of the battery. This current doesn't change the direction
The loudness of sound depends on: Amplitude of vibration. Area of vibrating body. Distance from the sounding body. Density of the medium.
A rectangular surface (0.14 m x 0.39 m) is oriented in a uniform electric field of 440 N/C. What is the maximum possible electric flux through the surface?
The fundamental particles: Although other atomic particles are known, the three fundamental ones are: Protons. The proton has unit mass and carries a unit positive charge.
The force is in Newton The buoyant (upward) force exerted by water on a submerged object is given by the formula F= ?Vg, where ? is the density of water (1.0 x 10 3 kg/m 3 ),

The temp gradient is similar to finding the slope of a line (when in two dimensions) Temp. Gradient= Change in Temp. value/Distance. dT/dx = (T2 - T1)/(X2 - X1)
