(a) Construct the wave function for hydrogen in the state n=4, l=3, m=2. Express your answer as a function of the spherical coordinates (r,theta,phi).
(b) Find the expectation value of r in this state. (You can use integral tables or a computer program to evaluate any non-trivial integrals.)
(c) If you could somehow measure the observable Lx2 + Ly2 on an atom in this state, what value (or values) could you get and what is the probability of each?
A 0.33-m-long violin string has a mass of 0.89 g. The peg exerts a 45 N force on it. Determine the lowest frequency sound produced by the vibrating sting

A 23 kg child goes down a straight slide inclined 38? above horizontal. The child is acted on by his weight, How large is the normal force of the slide on the child
Torque can be calculated by multiplying the force (N) applied at 90 degrees to the lever arm at a distance (m) from the pivot point (point of rotation), the compound SI unit for the torque is N*m. If the force (at 90 degrees to the lever arm) appl..
If linear momentum is conserved when there is no external force applied, how is angular momentum conserved
