The starship Voyager, like many other vessels of the newly designed 24th-century fleet, uses antimatter as fuel.
(a) How much energy is released when 1.00 kg each of antimatter and matter annihilate each other?
(b) When the antimatter is atomic antihydrogen, a small amount of it is mixed with excess atomic hydrogen (gathered from interstellar space during flight). The annihilation releases so much heat that the remaining hydrogen nuclei fuse to form 4He. If each hydrogen-antihydrogen collision releases enough heat to fuse 1.00×105 hydrogen atoms, how much energy (in kJ) is released per kilogram of antihydrogen?
(c) Which produces more energy per kilogram of antihydrogen, the procedure in part (a) or that in part (b)?
