Atrain travels due south at 30 m/s (relative to the ground) in a rain that is blown toward the south by the wind. the path of each raindrop makes an angle of 70° with the vertical, as measured by an observer stationary on the ground. an observer on the train, however, sees the drops fall perfectly vertically. determine the speed of the raindrops relative to the ground

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
