If two mass are kept in a distance d, both mass : 1)will attractive
2)will repulsive
3)Will do both
4)None of the above​

  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

your answer is, orbit around the nucleus
