70. An object is moving with an initial velocity of 23 m/s. It is then subject to a
constant acceleration of 3.5 m/s2 for 12 s. How far will it have traveled during
the time of its acceleration?

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)
