A 0.365-kg blue bead slides on a frictionless, curved wire, starting from rest at point circle a in the figure below, where h = 1.50 m. At point circle b, the blue bead collides elastically with a 0.620-kg green bead at rest. Find the maximum height the green bead rises as it moves up the wire.
A tiny piece of metal contains 100 magnetic spins. At room temperature, there is an equal likelihood for an individual spin to be "up" versus "down." What is the probability of finding the metal fully magnetized
A proton is released from rest inside a region of constant, uniform electric field E1 pointing due North. 27.3 seconds after it is released, What is the ratio of the magnitude of E2 to the magnitude of E1
what force is needed to pull a 150 pound sled along a horizontal surface? The coeficient of kinetic friction is 0.10 and the sled is pulled by a rope that makes the angle of 0 degree with the horizontal. There is no acceleration.
