Answer:
Gravitational potential energy,
Explanation:
Mass of an Egyptian pyramid,
It is placed 19 m above the surrounding ground, h = 19 m
We need to find the gravitational potential energy store in the pyramid. This energy is possessed by an object due to its position. It is given by :
So, the gravitational potential energy store in the pyramid is . Hence, this is the required solution.
