An electron is confined to a region of size 0.15 nm (i. e., infinite potential walls at either end). (a) (5 pts) what is the ground state energy in ev? (b) (5 pts) the electron falls from the 5th excited state to the 3rd excited state, emitting a photon in the process. what is the wavelength of the photon in nm?

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?

Ball bearings are made by letting spherical drops of molten metal fall inside a talll tower-called a shot tower- and solidify as they fall. a-if a bearing needs 4.0 s to solidify enough for impact, how high must the tower be? b- what is the bearing's impact velocity?
