An enclosure has an inside area of \(50 \mathrm{~m}^{2}\), and its inside surface is black and is maintained at a constant temperature. A small opening in the enclosure has an area of \(0.01 \mathrm{~m}^{2}\). The radiant power emitted from this opening is \(52 \mathrm{~W}\). What is the temperature of the interior enclosure wall? If the interior surface is maintained at this temperature, but is now polished so that its emissivity is 0.15 , what will be the value of the radiant power emitted from the opening?
