Which two characteristics determine the setrength of the gravitational force between two objects ? a. Th distance between the objects near edges

Which force is most responsible for binding together an atom's protons and neutrons? electrostatic gravitational nuclear magnetic

How much energy is supplied to each coulomb of charge that flows through a 12-v battery?

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?
