The total linear momentum of a bus of mass 4000 kg that is moving 9. at a speed of 25 m/s and a truck of mass 2000 kg that is moving at a speed of 20 m/s is kg · m/s.

the device is called “ rocket engine”

gas and liquid

  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
