Physics question
Could someone tell me the answer to these 2? It was on my sample practice exam and it's not right, I've even checked on chegg and other sources and they're roughly the same as mine but with variables in different places. I think the reason why I got the first one wrong was that I used P rather than rho but I have no idea why the bottom one is wrong.
I really just want to know the answer because it's worth 3 points and I don't want to get it wrong on the actual exam when it's here.
