Question:
A space satellite in the shape of a sphere is traveling in outer space, whereits surface temperature is held at 283.2 K. The sphere ‘sees’ only outer space, whichcan be considered as a black body with a temperature of 0 K. The polished surfaceof the sphere has an emissivity of 0.1. Calculate the heat loss per m^2 by radiation.
