Adog of mass 4 kg runs up a hill of height 8 m. how much gravitational potential energy does the dog gain? a.314 j b.229 j c.32 j d.78 j

The gravitational potential energy is 314 J.

(A) is correct option.

Explanation:  

Given that,

Mass of dog = 4 kg

Height = 8 m

We need to calculate the potential energy

Using formula of potential energy

m = mass

g = acceleration due to gravity

h = height

Put the value into the formula

Hence, The gravitational potential energy is 314 J.

this means that the temperature of both substances will be equal
