An automobile has a vertical radio antenna 1.10 m long. the automobile travels at70.0 km/h on a horizontal road wherethe earth's magnetic field is 50.0 µt, directed toward thenorth and downwards at an angle of 65.0° below thehorizontal.
(a) specify the direction the automobile should move in order togenerate the maximum motional emf in the antenna, with the top ofthe antenna positive relative to the bottom.

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
