Problem 14.69 Antihydrogen is the only antimatter element that has been produced in the laboratory, albeit just a few atoms at a time. Each antihydrogen atom consists of a positron in orbit around an antiproton and has the same atomic mass as hydrogen. If an antihydrogen atom collides with a hydrogen atom, they annihilate each other and create gamma radiation. Part A What minimum amount of energy released in this process? Express your answer using three significant digits. | ΑΣΦ + E= Submit Part B Request Answer Value Submit If this energy could be harnessed in a matter-antimatter automobile engine, how far could a car travel on 10 mg each of antihydrogen and hydrogen? At highway speeds, a typical automobile expends about 2.5 x 10³ J per meter. Express your answer with the appropriate units. Request Answer Units ? ? 10 of 10 J
