The average mass of rain drops is $\displaystyle 3.0 \times 10^{-5} \mathrm{~kg}$ and their average terminal velocity is $\displaystyle 9 \mathrm{~m} / \mathrm{s}$. Calculate the energy transferred by rain to each square metre of the surface at a place which receives $\displaystyle 100$ cm of rain in a year.
Official answer
(2)
$\displaystyle 4.05 \times 10^4 \mathrm{~J}$
