Consider the gasoline market. If the price of crude oil, an input in the production of gasoline, falls, what effect will this have on consumer surplus in the gasoline market? (Hint: Draw the demand and supply curves, identify CS and PS, shift the appropriate curve, and then see which answer is correct).

A flat rectangular loop of wire is placed between the poles of a magnet. It has dimensions w = 0.60 m and L = 1.0 m, and carries a current I = 2.0 A. The magnetic field due to the magnet is uniform and of magnitude 0.80 T. The loop rotates in the magnetic field and at one point the plane of the loop makes a 30° angle with the field. At that instant, what is the magnitude of the torque acting on the wire due to the magnetic field?
