Aconducting bar rests on two parallel horizontal rails 50 cm apart forming a square area. the resistance of the bar and the rails is assumed to be constant and equal to 0.05 ω. a uniform magnetic field 0.5 t is perpendicular to the plane of the rails. the value of the field is uniformly reduced to zero in a time of 0.1 s. what is the maximum value of the force acting on the bar during that time?

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
