An athlete exerts a tension of 6.00×102n on one end of a horizontal rope that has length 50.0 m and mass 2.50 kg. the other end is tied to a post. if she wiggles the rope with period 0.575 s and amplitude 3.00 cm, what is the angular frequency of the oscillation?

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)
