The Sun puts out 3.9 x 10^26 J of energy per second. Assuming 100% conversion to energy, how much mass is required to create this energy

Answer 1

I'm sorry, but I really, really need help with this, but it's due tomorrow and I'm so lost..

Answer 2

Start with

Energy= mass*speedlight^2
solve for mass. If speedlight is in m/s, and energy in joules, then mass will be in kilograms.

Answer 3

omg thank you for much!!! :>
