"a pendulum is made by letting a 2.0-kg object swing at the end of a string that has a length of 1.5 m. the maximum angle the string makes with the vertical as the pendulum swings is 30°. what is the speed of the object at the lowest point in its trajectory? "

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)
