it's just an exam. we all try our best anyways. Might be a hard paper, but that doesn't matter. whatever anyone gets is what they deserve no matter what. I'm aiming for an A, if i don't get the result, there are other ways that lead to rome.
Besides, that,
i am confused on particle exchange, with electron capture - why is it a W- boson? why not W+ which is for proton electron collision, i think
any tips
