The sun radiates about 3.6 x 1026 joules of energy each second. How much mass does the sun lose each second?
sub what you have into \(E=mc^2\) where E=3.6 x 1026J and c=3.0x10^8
where did you get 3.0*10^8
that is the speed of light, a constant.
ok so how would I solve this
the equation I've given is the einstein mass-energy equation. The mass lost = energy out/ c^2 sub energy out= 3.6 x 1026J into the equation and you get the answer.
