Determine the commutator [Lz ,Ly ] .
State the selection rules for allowed transitions in multielectrons atoms
The energy of a particle of mass m bound by a special kind of spring is
E = p2/2m + kx4
where k is a positive constant. Use the Heisenberg’s Uncertainty Principle to calculate the minimum possible energy of the particle.
Two events happen simultaneously in the frame S at a distance of 3.0 light years apart. In the frame S′, which is moving with a speed v relative to S, the distance between these events is 3.5 light years. Calculate (i) v and (ii) the time interval between these events in the frame S′
