Doug is driving a golf ball off the tee. his downswing takes 0.50sec from the top of the swing until ball impact. at the top of the swing, the club's angular velocity is zero; at the instant of ball impact, the club's angular velocity is 30rad/s. the swing moment of inertia of the club about the grip is 0.220kg*m^2. what average torque does doug exert on the golf club during the downswing? a. 13.2 b. 26.4 c. 64.6 d. 106.8

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
