If the emission rate of a blackbody at 0 ^@C is R , then the rate of emission at 273^@C is
The rate of emission of a black body at 0^(@)C is its rate of emission at 273^(@)C is
The rate of emission of radiation of a black body at 273^(@)C is E , then the rate of emission of raidiation of this body at 0^(@)C will be
The rate of emission of heat energy of an iron ball of radius 5 cm is 10 J/s, then rate of emission of heat energy by a copperr ball of radius 1 cm at same temperature will be (If emissivity of both the balls is same)
