Question
A spherical deep-space probe has a diameter of 65.0 cm. Inside the probe, electronic
components steadily dissipate 450 W of power. The emissivity of the probe's surface is
0.80. Calculate the surface temperature of the probe. Assume that there are no radiative
heat sources or surfaces near the probe and that the 450 W of power is distributed
uniformly over the surface of the probe.
