A particular space tether is a wire made from aluminum (resistivity 2.7×108 W×m, density 2700 kg/m3). Its mass is 10.0 kilogram and it moves perpendicularly through a uniform 20.0 T magnetic field at a speed of 6.81 × 103 m/s.

(a) Determine what power is produced by the tether's motion through the magnetic field? Hint: Use the definition of resistance in terms of resistivity and the definition of density.

(b) If the tether is 2 kilometer long with a uniform cross-section, determine what is the area of the cross-section?

(c) Determine what is the overall resistance of the 2 km long tether?
