A hot black body emits the enegy at the rate of 16 `Jm^-2s^-1` and its most intense radiation corresponds to 20000`Å`. When the temprerature of this body is further increased and its most intense radiation corresponds to `10000Å`, then find the value of energy radiated in `Jm^-2s^-1`.

A hot black body emits the energy at the rate of 16 J m^(-2) s^(-1) and its most intense radiation corresponds to suspension is vertically above the centre of the sphere. A torque of 0.10 N-m is required to rotate the sphere through an angle of 1.0 rad and then maintain the orientation. If the sphere is then released, its time period of the oscillation will be :

A black body having an area of 2xx10^(-4)m^(2) for its radiating surface radiates energy of 16.42 J in 15 minutes. What is the temperature of the body ?

A black body emits radiations of maximum intensity at a wavelength of 5000 A, when the temperature of the body is 1227° C. If the temperature of the body is increased by 2227 °C, the maximum intensity of emitted radiation would be observed at
