A 20 Kg box is being drug across the floor based on the diagram below determine the normal force the floor exerts on the box. ​

  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

80cm/s.

24cm/s.

53.3cm/s.
