The nucleus of an atom consists of protons and neutrons (no electrons). a nucleus of a carbonā12 isotope contains six protons and six neutrons, while a nitrogenā14 nucleus comprises seven protons and seven neutrons. a graduate student performs a nuclear physics experiment in which she bombards nitrogenā14 nuclei with very high speed carbonā12 nuclei emerging from a particle accelerator. as a result of each such collision, the two nuclei disintegrate completely, and a mix of different particles are emitted, including electrons, protons, antiprotons (with electric charge ā each), positrons (with charge + each), and various neutral particles (including neutrons and neutrinos). for a particular collision, she detects the emitted products and find 17 protons, 4 antiprotons, 7 positrons, and 25 neutral particles. how many electrons are also emitted?

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedesā principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.
