Answer:

2000 Joules

Explanation:

The formula for potential energy is P.E.=mgh (where M is Mass, G is acceleration due to Gravity, and H is Height)

Plug the numbers in to get P.E.=(10kg)(10m/s^2)(20m)

Multiply together to get 2000 joules

Just to correct you - the speed of light is 3.0 x 10^5 km/sec and not 105 km/sec as given by you (maybe it was just a typing mistake from your end).

The average distance between earth and moon would be - 384,000 kms.

This is calculated by the formula -> Distance = Speed x Time.
