The masses of the blocks are m1 = 16.0 kg and m2 = 12.0 kg, the mass of the pulley is m = 5.00 kg, and the radius of the pulley is r = 0.300 m. block m2 is initially on the floor, and block m1 is initially 4.60 m above the floor when it is released from rest. the pulley's axis has negligible friction. the mass of the string is small enough to be ignored, and the string does not slip on the pulley, nor does it stretch.

a/how much time (in s) does it take block m1 to hit the floor after being released?

b/how would your answer to part (a) change if the mass of the pulley were neglected? (enter the time, in seconds, it takes block m1 to hit the floor if the mass of the pulley were neglected.)

Acylinder with a movable piston contains 11.7 moles of a monatomic ideal gas at a pressure of 1.32×10^5 pa. the gas is initially at a temperature of 300 k. an electric heater adds 43200 j of energy into the gas while the piston moves in such a way that the pressure remains constant. cp=20.79 j k^−1 mol^−1 for a monatomic ideal gas, and that the number of gas molecules is equal to avogadro's number (6.022×10^23) times the number of moles of the gas. (a) what is the temperature of the gas after the energy is added? (b) what is the change in volume of the gas? (c) how much work is done by the gas during this process?

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 of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
