One hazard of space travel is debris left by previous missions. there are several thousand objects orbiting earth that are large enough to be detected by radar, but there are far greater numbers of very small objects, such as flakes of paint. calculate the force exerted by a 0.100-mg chip of paint that strikes a spacecraft window at a relative speed of 4.00Ă103m/s, given the collision lasts 6.00Ă10â8s.

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 1.00Âșc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in Ă10^{-3} â3 m)
