A student had a weight of 500N. When the student stands, the area of the feet in contact with the ground is 200cm^2. What pressure does the student exert on the ground?

explanation:

newton's third law, for every action there is an equal and opposite reaction.

  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
