a. At what temperature does a uniform spherical object of radius 15.0 cm, and surface emissivity e = 0.9, radiate 1260 watts of total power? b. If this same object suddenly contracts to the size of a sphere of radius 5.00 cm, but is radiating the same total power as in part a, what will be its new temperature? The Stefan-Boltzmann constant is o = 5.67 x 10 *W/(m² *K*).
