A 1-m wire with a mass of 90 g, is under tension. A transverse wave, for which the frequency is 370 Hz, the wavelength is 0.4 m, and the amplitude is 8.8 mm, is propagating on the wire. The time for a crest of this wave to travel the length of the wire is closest to

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)
