7C3H5(NO3)3 is an interesting, multi-purpose chemical compound. Nitroglycerin, also called nitro, is a heavy, colorless, poisonous, oily explosive. As a prescribed drug, it
helps relax and dilate blood vessels and is often used in treating chest pain. It is also
used in the manufacture of explosives, specifically dynamite, and is frequently used in
construction and demolition projects. How many atoms of oxygen are in a molecule
of nitroglycerin?

An alpha particle with kinetic energy 12.5 mev makes a collision with lead nucleus, but it is not "aimed" at the center of the lead nucleus, and has an initial nonzero angular momentum (with respect to the stationary lead nucleus) of magnitude l = p0 b, where p0 is the magnitude of the initial momentum of the alpha particle and b=1.40×10−12 m. (assume that the lead nucleus remains stationary and that it may be treated as a point charge. the atomic number of lead is 82. the alpha particle is a helium nucleus, with atomic number 2.) what is the distance of closest approach?
