A localized electron has been polarized so that its spin is oriented in the positive z- direction. It is now subject to the appl
ication of a constant uniform magnetic field B = Bî along x over a period of time of duration T. After that, it is subject to the application of another magnetic field of the same magnitude B but along y: B2 = Bý, also with duration T. (a) What is the probability P that the spin-flip would occur as a result? That is, what is the probability that the spin of the electron would be found oriented in the negative z-direction after the application of the magnetic fields is over? (b) Is it possible to find such duration that the spin-flip would occur with certainty: P = 1? If yes, what would be that time r?

Answer:
The total angular momentum is 292.59 kg.m/s
Explanation:
Given that :
Rotation of the horizontal circular platform = 0.919 rad/s
mass of the platform (m) = 90.7 kg
radius (R) = 1.91 m
mass of the poodle = 20.5 kg
Your mass = 73.5 kg
speed v = 1.05 m/s with respect to the platform
r = 0.955
Mass of the mutt = 18.5 kg
Your angular momentum is calculated as:
Your angular velocity relative to the platform is
For poodle :
Actual
Disk
Total angular momentum of system is:
L =
= (152.04 + 98.76 + 6.9003 + 34.89) kg.m/s
= 292.59 kg.m/s
