Hi everyone.
This is my first post, and this forum looks like it is full of science geniuses for some reason so please don't laugh at my stupid questions :P
This is NOT a HW question. I am self studying for my SAT physics and I can't afford a tutor, so any help would be appreciated. I have the answers, but not the explanations.
