The centre of mass, or centre of momentum, (CMS) frame is that in which the sum of the momenta (i.e., the total momentum) of all particles is zero. An electron has a kinetic energy K of 1 MeV and is incident on a proton at rest in the laboratory. The goal of this exercise is to calculate the speed of the CMS frame moving relative to the laboratory. (a) Express the initial energies Ee, Ep and initial momenta pe, pp...

When bungee jumping from a high bridge over Victoria Falls, an operator first attaches an elastic rope to the jumper. The jumper then jumps off the bridge, falling freely until they reach the unstretched length of the rope Then, the rope begins to stretch and slows the jumper to a stop. The rope pulls the jumper back up, and they oscillate up and down for a while until the operator pulls the jumper back up to the bridge. The rope...

Learning Objectives As part of this activity, you want to be able to: Experimentally verify that the strength of the Coulomb force between two charged bodies varies inversely with the square of the separation distance between them. Experimentally verify that the strength of the Coulomb force between two charged bodies varies with the product of the charges. 1.1 Pre-lab Gravitational force Last semester you may have encountered Newton's universal law of gravitation. This law, which describes the force between two...

Problem 4. Radiation from the black hole accretion disk.] In this problem you will find the temperature of an accretion disk surrounding the black hole, and the wavelength of maximal radiation from the disk. Note that the calculation is super-simplified - if you take more advanced astronomy courses, you will do the same calculation more carefully. In this problem 'BH' means black hole. We will consider the BH of mass equal to twenty solar masses MBH = 20 MSun. (a)...
