A metal sphere of radius 4.55 cm is at a temperature of 382 . C. The sphere is in a container that is held at a temperature of -90 C. The speher has an emissivity of e =0.5. Determine the net rate of energy being radiated from the sphere (in W). (The stephan-Boltzmann Constant is o = 56.7n- W m2 K 4 , the n is nano)
