The more familiar proton is made up of two up quarks and one down quark. By mass-energy equivalence, the collision of two protons can yield two protons and two kaons, with some kinetic energy This problem has been solved! buffey curtisA quark is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei. All commonly observable matter is composed of up quarks, down quarks and electrons. Owing to a phenomenon known as color confinement, quarks are never found in isolation; they can be found only within hadrons, which include baryons (such as proton… buff experiencia wow
