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.
In general the total energy of a harmonic oscillator having of two parts, potential energy (P.E) and kinetic energy (K.E.), the former being because of its displacement from the m
how dielectric mat is used for high voltage safety ? how it works?
give examples of like and unlike parallel forces
sir in books like hc verma i have seen if centre of mass remains at rest... then mx = mX...how?
Refractive Index: The ratio of sine of angle of incidence to the sine of angle of refraction is constant for all rays passing single medium to another medium. This constant is
Evaluate the volume of water in a round reservoir approximately 1 km in radius, if the depth of the water is 15 m. Approximately how many balls with a diameter of 1.8 cm should
what are the structure of the seeds
(Assume the metallic ball is spherical with a diameter d = 2.5 cm. Let''s also assume it is made out of nickel, which has a density of roughly 9 g/cm 3 .) After it first touches
Ferromagnetic materials get magnetic properties not only because their atoms owns a magnetic moment but also because the material consists of small regions called as magnetic domai
It is the degree to which a object is magnetized when placed in a magnetic field. It can also be described as the pole strength per unit cross sectional area of the object or th
