Two identical particles of mass m are trapped in one dimension in an infinite square well potential of width a. the particles do not interact. (a) write down the single particle energies (one for each particle) of the ground state and the first excited state of the two-particle system. consider first two bosons and then two fermions.

Agroup of students were investigating the force of gravity. they began by dropping a foam ball from a height of 3 meters into a bucket of sand. the ball hit the sand in 0.306 seconds. they dropped additional balls of approximately the same diameter, but of different masses. here is the data they collected. based on this experiment and the collected data, what would their conclusion be?
