Question

The height of a waterfall is 20 and 2×10^6 kg of water falls from it in a minute. Calculate power

Answer 1

Answer:

Power  is $6.53\times 10^6 W$

Explanation:

Quantity o of water $m= 2 \times 10^6kg$

Height  of water fall h=20 m

Time taken t=1 min = 60 s

$Power=\frac{Work}{time}\\P=\frac{mgh}{t} \\P=\frac{2 \times 10^6 \times 9.8\times 20}{60} \\P=6.53\times 10^6 W$

Power is  $6.53\times 10^6 W$
