those of you are studying with examkrackers, need a bit of help.
physics lecture test 5, question 103: can someone explain this to me, the explanation they give aren't cutting it. they seem to get numbers out of no where!
also, same test, question 108. wouldn't answer choice A also be a correct answer. looking at the equation, a higher density will just cancel out with eachother.
thanks!
