(D) The power $P$ is given by the formula $P = \frac{W}{t} = \frac{mgh}{t}$.Given: $P = 2 \, kW = 2000 \, W$,$g = 10 \, m/s^2$,$h = 10 \, m$,and $t = 1 \, 	ext{minute} = 60 \, s$.Rearranging the formula to solve for mass $m$:$m = \frac{P 	imes t}{g 	imes h} = \frac{2000 	imes 60}{10 	imes 10} = \frac{120000}{100} = 1200 \, kg$.Since the density of water is $1000 \, kg/m^3$,the volume $V$ in cubic meters is $V = \frac{m}{ho} = \frac{1200 \, kg}{1000 \, kg/m^3} = 1.2 \, m^3$.Since $1 \, m^3 = 1000 \, liters$,the volume in liters is $1.2 	imes 1000 = 1200 \, liters$.

Power of a water pump is $2 \, kW$. If $g = 10 \, m/s^2$,the amount of water it can raise in one minute to a height of $10 \, m$ is .............. $liter$.
