this question. We're looking at the nuclear fusion off protons. We've a kilim tree you're trying to give us here before, and a positron you know, find what is the energy that's being released. We are you at a Q value, which is the change in the mess off the show victims to the final products multiplied by C square. So the changing mass define s u mass off hydrogen that's mess off. Young tree subjected by mass off four and myself T electron. All right, so this will tell us how much demands is actually committed from the initial reluctance. Did you find a product? And this this lost in mess is X accommodated to energy, and that is the energy that's being released to work on a UCSD messes off all of this nuke lights. So a mess of the new clients can be phone to all my resources meself. He didn't treat you right? Yes, off helium for she said, l far particle in a CD mass off the actual just well here. So pretty to co creator. We use our C Square to be 91.494 MTV put you for convenience since we're using in terms off atomic mess units. Right? And we should get on finance. ER would be 18.8 MTV.
