Answer 2

Given:

Mass - 1 kg of water

Altitude(height) - 1200 m

To find:

potential energy

Solution:

Mass - 1 kg of water

Altitude(height) - 1200 m

The formula for Energy is:

$Potential \: Energy = mgh$

acceleration due to gravity= 9.8 m/s² at the surface of the earth.

The constant value of acceleration due to gravity will be used which is 9.8m/s².

$Potential \: Energy = 1 \times 9.8 \times 1200$

adding the values to the formula of potential energy,

$Potential \: Energy = (9.8 \times 1200)J$

$Potential \: Energy = 11760J$

Therefore, the potential energy of one kg of water at KJ at an altitude of 1200 m is 11,760Joules.
