Question

In physics the mass energy equivalence is that the mass of a body is measured by its energy

content. This may be written algebraically as E=mc2
, where E is energy, m is mass, and c is the
speed of light in a vacuum. Transform the equation so that it will be read as a solution for mass,
m. Show all the steps

Answer 1

E = mc^2...divide both sides by c^2
E / c^2 = m

Answer 2

Answer: The energy equation is
`E = mc^(2)`, if you want the solution for mass, then you want the mass alone in one side of the equation. You can do this in the next way:

`E = mc^(2) - >(E)/(c^(2) ) = (m)/(c^(2) ) *c^(2) = m`

where i divided by c square in both sides of the equation.

Then if you know the mass energy of an body (and the velocity of the light), with the equation
`m = (E)/(c^(2) )` you can obtain the mass of such body.
