Two boats pull a 75.0 kg water skier with a 45° from the skier to each boat (90° between altogether). (a) If each boat pulls with a force of 600 N and the skier travels at a constant velocity, what is the magnitude of the resistance force from the water on the skier? (b) Assuming the resistance force remains constant, if the boats now pull with a force of 700 N each what is the magnitude of the acceleration of the skier?

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)

Which of the following conditions lead you to see an absorption line spectrum from a cloud of gas in interstellar space? the cloud is extremely hot. the cloud is visible primarily because it reflects light from nearby stars. the cloud is cool and lies between you and a hot star. the cloud is cool and very dense, so that you cannot see any objects that lie behind it.
