could affect uf old man except during take-off and landing, when they are closer to e typically 150 mph, Does the kinetic equation explain why there are few survivors in an airplane crash? 7. Energy is conserved-that is a law of physics. Why then do our leaders beseech us to "conserve energy"? 8. Although TNT has very little relative energy per gram, it is a highly effective explosive. Explain why, briefly. 9. Some people say that the United States is "addicted" to gasoline. Compare gasoline to alternative ways of powering an automobile. Describe both the advantages and disadvantages of the alternatives you discuss, compared to a gasoline engine. Multiple-Choice Questions 1. "Smart rocks" are considered for A. geologic dating B. ballistic missile defense C. nuclear power D. solar power One watt is equivalent to: A. one joule/second B. one coulomb/second Since there are typically 30 days per month, that means that there are 30 x 24=720 month. So-the industrial plant uses 720 times as much energy as 50 houses. As stated ing t. 50 houses typically use 50 kilowatts. So this would imply that the power plant uses 720 uwatts = 36 megawatts. Recall that a typical large power plant produces I gigawant zawatts, The usage of the industrial plant seems quite small compared to this. Yet the off ement made the usage appear quite large (at least that was my interpretation)
