What is the gravitational potential energy of a book with a mass of 0.30 kg on a 1.0 m high desk?

3.0

Same explanation as the person above but the significant figures must be considered in physics.

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.

their crystal patterns have been disrupted by stress
