Answer:
1 x 10¹²J
Explanation:
Given parameters:
Mass of the water pumped = 2.05 x 10⁸kg
Height = 500m
Unknown:
Potential energy = ?
Solution:
The potential energy amassed by water at this height is expressed as;
P.E = mgH
m is the mass
g is the acceleration due to gravity
H is the height
Insert the parameters and solve;
P.E = 2.05 x 10⁸ x 9.8 x 500 = 1 x 10¹²J
