The flywheel of a steam engine runs with a constant angular speed of 113 $rev/min$. when steam is shut off, the friction of the bearings and the air brings the wheel to rest in 1.0 $h$. what is the magnitude of the constant angular acceleration of the wheel in $rev/min^2$? do not enter the units.

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)
