2–105 The outer surface of a spacecraft in space has an emis- sivity of 0.6 and an absorptivity of 0.2 for solar radiation. If solar radiation is incident on the spacecraft at a rate of 1000 W/m, determine the surface temperature of the spacecraft when the radiation emitted equals the solar energy absorbed.
