A black body emits `10` watts per `cm^(2)` at`327^(@)C`. The sun radiates `10^(5)` watt `per cm^(2)`. Then what is the temperature of the sun ?

A body at 300^(@)C radiates 10^(5) watt/ m^(2) . If the sun radiates 10^(9) watt/ m^(2) , then its temperature will be (if both bodies are considered as black)

A body at 300^(@)C radiates 10 J cm^(-2) s^(-1) . If Sun radiates 10^(5) Jcm^(-2) s^(-1) ,then its temperature is:

A black body at a temperature of 227^(@)C radiates heat energy at the rate of 5 cal/ cm^(2) -sec. At a temperature of 727^(@)C , the rate of heat radiated per unit area in cal/ cm^(2) -sec will be

A black body at temperature 227^(@)C radiates heat at the rate of 5 cal/ cm^(2) , at a temperature of 27^(@)C , the rate of heat radiated per unit area per unit time in cal/ cm^(2) s, is

The temperature of the sun is 6000 K and is treated as a black body. The solar heat energy radiated by the sun is 10^(9)W//m^(2) . What is the temperature of a black body if it radiated heat energy of 10^(5)W//m^(2) ?

If the rate of loss of solar energy by radiation is 4.48 xx 10^(36) watt and the radius of the sun is 6.95 xx 10^5 km, what will be the temperature of the sun ?

A spherical black body with a radius of 12 cm radiates 450 watt power at 500 K. If the radius were halved and the temperature doubled, the power radiated in watt would be
