Dapted from example by Walker.) A rectangular wire loop with 200 turns has a side of width 4.00 cm oriented parallel to the x-axis and a side of height 5.00 cm parallel to the y-axis. A uniform magnetic field points in the x-direction with magnitude 0.350 T. The current around the loop is 1.60 A. Compute the torque on the wire loop around its vertical axis in two ways: a) By computing the magnetic (Lorentz) forces acting on each leg of the loop and using these to compute the net torque on the loop. b) By computing the magnetic dipole moment vector and using this to compute the net torque on the loop.

Water at room temperature of 20.0°c is poured into an aluminum cylinder which has graduation markings etched on the inside. the reading in the graduations is 300.0 cc. the cylinder with the water in it is then immersed in a constant temperature bath at a temperature of 100°c. what is the reading for the level of water on the graduations of the cylinder after the water and the cylinder reach thermal equilibrium with the bath? the volume coefficient of expansion of water is 2.07 x 10^-4 k-1, and the linear coefficient of expansion of aluminum is 23.0 x 10^-6 k-1. a) 305.0 cc b) 304.0 cc c) 303.5 cc d) 303.3 cc e) 304.5 cc
