A spherical body of area A and emissivity e=0.6 is kept inside a perfectly black body. Total heat radiated by the body at temperature T

A spherical body of area A and emissivity e=0.6 is kept inside a perfectly black body. Total heat radiated by the body at temperature T

A spherical body of area A and emissivity e=0.6 is kept inside a perfectly black body. Total heat radiated by the body at temperature T

A spherical body of area A, and emissivity e = 0.6 is kept inside a black body. What is the rate at which energy is radiated per second at temperature T

A spherical body of emissivity e, placed inside a perfectly black body (emissivity = 1) is maintained at absolute temperature T. The energy radiated by a unit area of the body per second will be ( sigma is Stefan's constant)

A body with surface area (A), temperature (T) and emissivity (e) = 0.6 is kept inside a spherical black body. What will be the maximum energy radiated ? [ sigma is Stefan's constant]

A black body of surface area 5cm^(2) , is kept at 127^(@)C . The rate of energy radiated by it is E. If its temperature is increased to 527^(@)C , then the increase in the rate of energy radiation will be

A body of surface area 10 cm^2 and temperature 727^@C emits 300 J of energy per minutes.Find the emissivity.
