fun than practical). 3. The Z machine at Sandia National Laboratory in Al- buquerque, New Mexico, is used to perform various physics experiments. Over the span of about 95 ns (nanoseconds) it delivers an electromagnetic pulse with a peak power of 350 TW (terawatts). This peak is more power than any other generator can produce and, in fact, is more than one-percent of the power produced by all the generators in the world combined. Let us assume the power varies linearly from zero up to a peak of 350 TW in 47.5 ns and then varies linearly back to zero after another 47.5 ns. (a) How much energy, in joules, is delivered by a single "shot" of the Z machine? (b) In terms of chemical energy, a kilogram of bacon contains approximately 4700 food Calories. Which has more energy, a Z-machine shot or a kilogram of bacon? (Food Calories are actually kilocalories and there are 4184 joules per kilocalorie.)
