Question

question 4 (2 points)
(02.01 mc)
e = mc²
c =?
○ a e/m
○ b m/e
○ c √(e/m)
○ d √(m/e)

Explanation:

Step1: Isolate $c^{2}$

Given $E = mc^{2}$, divide both sides by $m$ to get $c^{2}=\frac{E}{m}$.

Step2: Solve for $c$

Take the square - root of both sides. Since $c$ represents the speed of light (a non - negative quantity in the context of the physical formula), $c=\sqrt{\frac{E}{m}}$.

Answer:

C. $\sqrt{(E/m)}$
