An office window has dimensions 3.5 m by 2.1 m. as a result of the passage of a storm, the outside air pressure drops to 0.96 atm, but inside the pressure is held at 1.00 atm. what is the magnitude of the net force pushing the window to the outside?

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)
