the Space shuttle lost a satellite which was being towed by a long conducting cable through the Earth's magnetic field. The cable was 12.2 miles in length, and the shuttle was moving at 18,500 miles per hour. Assume that the cable was moving perpendicular to the Earth's magnetic field of 5.50 x 10^(-5) T, and calculate the voltage generated.

Hmmm..
All is nice, but for electricity to flow we need a closed circuit. It is a fundamental oversight.
By compleating the circuit we may have
Ve=vBL
Ve- voltage induced
v - velocity
B - magnetic field steangth
L - effective length of the conductor
L=12.2 miles= 19634meters
V=18500mph= 29772864 mph or 8270 m/sec
Finally since Ve=vBL
Ve=8270 x 5.50 E-5 x 19634=
Ve=8930 Volts
