Question

How much mass does the sun lose through nuclear fusion per second?

Answer 1

1.10^6 kg of mass per second

Step-by-step explanation:

All energy lost by the sun comes from nuclear fusion.

Sun loses energy at 2.5*10^{19}J per hour, that is 9*10^{22}J/s

To find the mass lost by the sun in liberation of energy you use the famous Einstein's equation:

`E=mc^2\\\\m=(E)/(c^2)=(9*10^(22))/((3*10^(8)m/s)^2)=1*10^6kg`

hence, the sun liberates 1.10^6 kg of mass per second
