Question
Assume that the total surface area of a human body is $1.6 \mathrm{~m}^2$ and that it radiates like an ideal radiator. Calculate the amount of energy radiated per second by the body if the body temperature is $37^{\circ} \mathrm{C}$. Stefan constant $\sigma$ is $6.0 \times 10^{-}$ ${ }^8 \mathrm{Wm}^{-2} \mathrm{~K}^{-4}$.
