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 1.00ΒΊc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in Γ10^{-3} β3 m)

Two masses are connected by a rope that hangs over a pulley as shown below. the pulley is a uniform cylinder of radius ν
=0.381meters and mass ν=3.1νν. initially ν"is on the ground and ν#rests 2.5 meters above the ground. if the system is released, use conservation of energy to determine the speed of ν#just before it strikes the ground. assume the pulley bearing is frictionless.
