Question

how much energy stored in 4m^3 water collected in a reservoir at a height of 30m

Answer 1

Answer:

     E=1.17 ×$10^{6}$J 0r 1176000J

Explanation:

Given Data:

Volume=4m^3

Height=30m

Find Out:Energy=?  

Solution:

Volume=mass/density

4=mass/1000

mass=4000kg

       P.E=mgh

     =4000 ×9.8 × 30

    E =1.17 ×$10^{6}$J 0r 1176000J
