An alpha particle with a kinetic energy of 13.0 mev makes a head-on collision with a gold nucleus at rest. part a: what is the distance of closest approach of the two particles? (assume that the gold nucleus remains stationary and that it may be treated as a point charge. the atomic number of gold is 79, and an alpha particle is a helium nucleus consisting of two protons and two neutrons.)

Will give brainliest! which statement best describes the difference between strong nuclear forces and weak nuclear forces? weak nuclear forces are involved when certain types of atoms break down. strong nuclear forces are responsible for holding atoms' nucleus together. weak nuclear forces hold bonds between atoms together. strong nuclear forces hold together the nucleus of an atom. strong nuclear bonds prevent atoms from falling apart. weak nuclear bonds prevent compounds from falling apart. strong nuclear forces are involved in breaking electrons from their shells. weak nuclear forces hold protons in the nucleus.
