A45 kg block is at rest on a 40o slope. a force of 430 n is acting on the block up the slope parallel to it. the block does not slide up the slope, what is the minimum value of the coefficient of static friction between the block and the slope?

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.

explanation:

considering the bohr theory, the type of connection that requires the transfer the answer conuldn't be right
