# Question

Einstein’s famous mass– energy equivalence is expressed by the equation E = mc2, where E is energy, m is mass, and c is the speed of light.

(a) What are the SI base units of energy?

(b) Another equation for energy is E = mgh, where m is mass, g is the acceleration due to gravity, and h is height. Does this equation give the same units as in part (a)?
