Question

which equation represents mass - energy equivalence?
e = m²c
e = mc²
e = (mc)²
e = mc

Explanation:

Einstein's mass - energy equivalence principle states that energy (\(E\)) is equal to mass (\(m\)) times the speed of light (\(c\)) squared. This is a fundamental concept in physics.

Answer:

\(E = mc^{2}\) (the second option)
