???????

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, in \( \mathrm{K} \) ? 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, in W? \[ \begin{array}{l} T_{s}=\quad \mathrm{K} \\ q_{\mathrm{rad}}=\mathrm{W} \\ \end{array} \]
