Two identical particles are in an isotropic harmonic potential. Show that, if the particles do not interact and there are no spin-orbit forces, the degeneracies of the three lowest energy values are 1, 12, 39 if the particles have spin 1/2, and 6, 27, 99 if the particles have spin 1.
What is exactly a Dobson an telescope, and what are the differences among this technical choice over a Schmidt-Cass grain or a Newtonian configurations?
A textbook of mass 1.91 kg rests on a frictionless, horizontal surface. compute the tension in the part of the cord attached to the book
A 21.0-kg box rests on a frictionless ramp with a 14.3° slope. The mover pulls on a rope attached to the box to pull it up the incline. If the rope makes an angle of 38.4° with the horizontal, what is the smallest force F the mover will have to exert..
A 150 g copper bowl contains 220 g of water, both at 200 degrees Celsius. Avery hot 300 g of copper cylinder is dropped into the water, causing the water to boil, with 5.00 g being converted to steam the final temperature of the system is loo degrees..
A man of mass 71.6 kg is forced to stand on the very end. If the end of the board drops by 5.60 cm because of the man's weight, find the shear modulus of the wood.
Explain why Newton's First Law and the Law of Conversation of Momentum are essentially saying the same thing in different ways. Why is it useful to have these two ways of saying it?
The space of an ion in a particle accelerator is doubled from 0.4500c to 0.9000c. The particles initial relativistic momentum is 472.819 MeV/c. Find the magnitude of its final relativistic momentum
Helium-Neon laser: "Lambda"= 632.8nm. We can observe the first order maximum at "theta"= 25 degrees. What is the second order maximum angle
