7. What is the change in gravitational potential energy for a 120.80-kg giant walking down a hill from a height of 21.23 m to 9.65 m?

Explanation:

It takes 1200 J of work to lift a car high enough to change a tire.

the force on the thing and the distance the force moves the thing

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is
