One light-hour is the distance that light travels in an hour. how far is this, in kilometers? (recall that the speed of light is 300,000 km/s.) ) 18 million kmb) 1.08 billion kmc) 300,000 kmd) 9.46 trillion kme) 100 million km

  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
