A black body at high temperature emits thermal radiations of

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

A black body, at temperature T K emits radiation at the rate of 81 W/m2. It the temperature falls to t=T/3 K. then the new rate of thermal radiation will be

A black body at a high temperature T radiates energy at the rate of E. When the temperature falls to T/2,the radiated energy will be

When a black body is heated, it emits heat radiations of

A hot water radiator at 310 K temperature radiates thermal radiation like a black body. Its total surface area is 1.6m^(2). Find the thermal power radiated by it.
