Answer:
Energy and Mass are interchangeable. That means the energy and mass are convert to one another.
Einstein submitted a special theory that develops a nuclear power, where the energy become a mass and mass become an energy.
E = mc² OR E/c² = m
Where
E stands for energy, (Joules)
m stands for Mass (Kg) and
c stands for speed of light (m/s)
where speed of light is constant, therefore E and m are mutually convertible
Also we find that the units on both sides of the equation are balanced
