Question: A solar collector is placed in direct sunlight where it absorbs energy at the rate of 880 J/s for each square meter of its surface.

A solar collector is placed in direct sunlight where it absorbs energy at the rate of 880 J/s for each square meter of its surface. The emissivity of the solar collector is e = 0.75. What equilibrium temperature does the collector reach? Assume that the only energy loss is due to the emission of radiation.
