A cart of mass 2.3 kg is moving with a velocity of 15.2 m/s. It makes a head-on perfectly inelastic collision with a stationary cart B with mass 8.1 kg causing them to travel with a velocity 10.94 m/s. What is the velocity of cart B?
Calculate the magnetic moments that are possible for the n=3 level of Hydrogen, making use of the quantization of angular momentum. You may neglect the existence of spin. Compare this with the Bohr prediction for n=3.
