Question

energy and mass are related by the formula e = mc². m is the mass of the object. c is the speed of light. which equation finds m, given e and c? a m = e - c² b m = ec² c m = c²/e d m = e/c²

Explanation:

Step1: Isolate m in formula

Given $E = mc^{2}$, we want to solve for m.

Step2: Divide both sides by $c^{2}$

$\frac{E}{c^{2}}=\frac{mc^{2}}{c^{2}}$, so $m=\frac{E}{c^{2}}$.

Answer:

D. $m = \frac{E}{c^{2}}$
