6. Current in length of copper wire.
Two students hold a 7.6 m length of copper wire horizontally, in an east-west direction, in the school yard. The wire is
moved vertically downwards at a speed of 0.30 ms?
Given that, in this yard, the horizontal component of the Earth's magnetic field is 4.0 x 10-5 T, and perpendicular to the
wire, calculate the emf detected, to two significant figures, by a very sensitive meter placed across the ends of the wire.

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 1.00ΒΊc. note that this calculation is only approximate because ocean warming is not uniform with depth. (answer in Γ10^{-3} β3 m)
