A charged particle of mass m is exposed to a constant magnetic field of magnitude B and directed out of the page, in which the particle moves in a clockwise circle of radius R with a speed v, as shown. What is the direction of the force show it by adding an arow?

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
