Several questions - 5-Three galaxies are aligned along an axis in order A, B, C. An observer in galaxy B is in the middle and observes that galaxies A and C are moving in opposite directions away from him, both with speeds 0.59c. What are the speeds of galaxies B and C as observed by someone in galaxy A?
c (galaxy B)
c (galaxy C)

What minimum barrier thickness is there no reflection? - I have a test coming up and I was told I need to know how to work out a problem like this:
Suppose electrons with E= 13.0 eV approach a potential barrier of height 6.0 eV.
For what minimum barrier thickness is there no reflection?
For what minimum barrier thickness is the reflection a maximum?
Values of the radius - Find the lesser and greater values of the radius where the n = 2, l = 0 radial probability density has its maximum values.
Probability of an electron - For a hydrogen atom in the ground state, what is the probability to find the electron between 1.03a0 and 1.04a0?
Probability of an electron - Calculate the probability of an electron in the ground state of the hydrogen atom being inside the region of the proton. (For purposes of calculation, use a proton radius r = 0.990 10-15 m.)
