A15 kg television sits on a shelf at a height of 0.3 m. how much gravitational potential energy is added to the television when it is lifted to a shelf of height 1.0 m?

Added energy to the television, E'' = 102.9 J

Explanation:

Given that,

Mass of the television, m = 15 kg

It is at a height of, h = 0.3 m

Potential energy at this height is given by :

E = m×g×h

E = 44.1 J

When it is at a height of, h' = 1 m

Potential energy is given by :

E' = m×g×h

E' = 147 J

So, added potential energy is, E'' = E'-E

E'' = 147 J - 44.1 J

E'' = 102.9 J

So, 102.9 J of energy is added to the television. Hence, this is the required solution.

hope this you out ^w^

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat
