An electric generator consists of a circular coil of wire of radius 4.0×10−2 m , with 20 turns. the coil is located between the poles of a permanent magnet in a uniform magnetic field, of magnitude 5.0×10−2 t . the b field is orientated perpendicular to the axis of rotation. the ends of the coil are connected via sliding contacts across a resistor of resistance 1.5 ω. the peak current measured through the resistor is 3.0×10−3 a. what is the angular frequency ω at which the coil is rotating? in rad/s to two sig figs.

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
