25.6

Explanation

The question asks us to calculate the gravitational potential energy of a brick being held above the surface of the Moon. Gravitational potential energy (PE) can mathematically expressed as follows: where:- stands for Potential Energy, which we need to find.- is the mass of the object, which in the problem is stated as 8 kilograms.- is the accelerated due to gravity, given for the Moon as 1.6 .- is the height above the Moon’s surface, which is given as 2 meters in the problem.Substitute the known values into the equation and solve.
