a water tank is 40m high and contains 4,000 kg of water .What is the gravitational potential energy of the water?show your work with the GUESS method

Respuesta :

Answer:

Explanation:

P.E = mgh

m = 4000kg, h = 40m, g = 10m/s^2

P.E = 4000 × 40 × 10

= 1600000J

Answer:

1568000 jule

Explanation:

Gravitational potential energy,

Ep=mgh=40m×4000kg×9.8m/s^2
