Two passengers are on a moving sidewalk at the airport. Passenger A is standing still while passenger B is walking with a speed of 2.0 km/h. The sidewalk is moving west at a speed of 1.5 km/h. From the perspective of passenger B, what is the speed of passenger A?

  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
