"A rule of thumb for estimating the distance in kilometers between an observer and a lightning stroke is to divide the number of seconds in the interval between the flash and the sound by 3. Is this rule correct? 1. No; the speed of sound varies rapidly with altitude. 2. Yes; the speed of light is much greater than the speed of sound. 3. Yes; the sound waves are longitudinal waves. 4. No; the speed of light must be considered in this problem".

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)
