An emf of 76.5 V is induced in a planar, circular loop of wire with 500 turns when a magnetic field of 0.45 T is quickly applied at an angle of 54 degrees to the normal of the loop. If it takes 0.12 s to turn on the field, what is the radius of the coil?

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 of a column of water 1.00 km high for a temperature increase of 1.00ºc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in ×10^{-3} −3 m)
