What is the Gravitational Potential Energy of a 30kg block resting 5m above the ground? O 150 J
O 1500 )
O 6J
O 60)

1470J

Explanation:

Given parameters:

Mass of the block  = 30kg

Height  = 5m

Unknown:

Gravitational potential energy  = ?

Solution:

The Gravitational potential energy of body is due to its position above the ground level.

 Gravitational potential energy  = mass x acceleration due to gravity x height

So;

Gravitational potential energy  = 30 x 9.8 x 5 = 1470J

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
