Two identical point charges of +Q are separated by a distance of 10cm
I) calculate the work done per unit charge to bring up another charge from far away along a perpendicular bisector of the line joining two charges to the point Midway between the charges.
ii)if one of the charges in part(a)is charged from +Q to -Q, calculate the work done per unit charge to bring up a charge to the same position as above

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
