It has been proposed that extending a long conducting wire from a spacecraft (a "tether") could be used for a variety of applications, from navigation to power generation. one of the first such experiments involving this technique was an august 1992 space shuttle flight, but the tether failed and only only 250 m of the conducting wire could be let out. a 40.0 v motional emf was generated in the earth’s 5.0 × 10-5 t field, while the shuttle and tether were moving at 7.80 × 103 m/s.

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
