Solution:
According to Stefan-Boltzmann law, the rate of emission of radiant energy by a black body is proportional to the fourth power of its absolute temperature, $E \propto T^4$. Here, $T = 500 \text{ K}$, so $E \propto (500)^4$.
A black body is at a temperature of $500 \text{ K}$. It emits energy at a rate which is proportional to: (1997)
