Calculate the temperature of the black body from given graph.

Calculate the value of solar constant at the distance of Jupiter, which is 5.2AU away from the sun. Hence calculate the temperature of a black body on Jupiter's Stefan's law.

At high temperature black body spectrum is .

Calculate temperature at perfectly black body radiates energy at the rate 5.67 xx 10^4 W/m^2 .

In a dark room with ambient temperature T_(0) , a black body is kept at a temperature T . Keeping the temperature of the black body constant (at T ), sunrays are allowed to fall on the black body through a hole in the roof of the dark room. Assuming that there is no change in the ambient temperature of the room, which of the following statements (s) is/are correct ?
