The famous Stefan's law of radiation states that the rate of emission of thermal radiation per unit by a black body is proportional to area and fourth power of its absolute temperature that is Q=sigmaAT^(4) where A = area, T = temperature and sigma is a universal constant. In the 'energy-length-time temperature' (E-L-T-K) system the dimension of sigma is

The amount of thermal radiation energy emitted from the surface of a body is found to be proportional to the ........ power of the absolute temperature of the body.

A black body, which is at a high temperature TK thermal radiation emitted at the rate of E W//m^(2) . If the temperature falls to T/4 K, the thermal radiation emitted in W//m^(2) will be

A black body, which is at a high temperature TK thermal radiation emitted at the rate of E W//m^(2) . If the temperature falls to T/4 K, the thermal radiation emitted in W//m^(2) will be
