The Stefan-Boltzmann law describes the power radiated from a black body in terms of its temperature. Namely, J = CT where J is the black-body radiant exitance, c is the Stefan-Boltzmann constant, and T is the thermodynamic temperature. A group of Canadian physicist recently discovered a strange low-temperature object whose temperature T ~ Uniform (2, 5). What is the mean My of the radiant exitance J? (A) MI = 618.6c (B) MI = 3.5c (C) MI = 206.2c (D) MI = 10.5c (E) N/A
