Consider two different situations. in situation a, a box of mass m on a frictionless tabletop is being pulled by a constant horizontal force f = m g. in situation b, a box of mass m is on a frictionless tabletop and a string of negligible mass runs over a peg of negligible friction, to a hanging mass m which is allowed to fall.

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)
