Suppose you are on a rooftop and you throw a ball downward to the ground with an initial speed v0. You then throw an identical ball upward with the same initial speed v0. After rising, this ball also falls to the ground. When each ball strikes the ground, which ball has the larger speed

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 (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to
