Question

Energy and mass are related by the formula E = mc^2

m is the mass of the object.
c is the speed of light
Which equation finds m, given E and c?

M = E - c^2
M = Ec^2
M = c^2/E
M = E/ c^2

Answer 1

M = E/ c^2 i hope i helped

Answer 2

m = E/c^2

Explanation:

To solve the given equation for m, divide by its coefficient.

`E=mc^2\\\\(E)/(c^2)=(mc^2)/(c^2)\\\\(E)/(c^2)=m`
