A motor can fill a tank, which is at a height of 10 m above the ground in 4 minutеs. Capacity the tank is 2400 kg of the water. Find the power of motor.  (g=10N/kg)
A) 100 W 
B) 1000 W 
C) 500 W
D) 250 W

$P=\frac{A}{t}$                $A=W=mgh$            $P=\frac{mgh}{t}$

$P=\frac{2400*10*10}{4*60}=1000\;\text{Вт}$
