Water falls from a height of $\displaystyle 200$ m into a pool. Calculate the rise in temperature of the water assuming no heat dissipation from the water in the pool.
(Take $\displaystyle \mathrm{g}=10 \mathrm{~m} / \mathrm{s}^2$, specific heat of water $\displaystyle =4200 \mathrm{~J} /(\mathrm{kg} \mathrm{K})$ )
Official answer
From NTA’s final answer key for this paper.
