f a roller-coaster car has 60,000 J of gravitational potential energy when at rest on the top of a hill, how much kinetic energy does it have when it is ¾ of the way down the hill so only ¼ of the track is left?

  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

this would be about 43%

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it
