I. Calculation Section Consider the decay of-- into π- and N, Assume : decays froln rest and calculate the kinetic energies of the π and Ao and then their speecls. You will need to look up the rest masses of the three particles in your textbook (or on Enforce momentum conservation and energy conservation. Use the relativistic formula- tion (Hint: The algebraic approach I used in class was to write down the energy conservation condition and the momentum conservation condition, plug the latter into the former, and solve for the mt This is ac- tually a bad way to solve the problem because, as you saw, there is a nightmare of square roots to deal with The way to avoid that, is to do the opposite i.e. write the momentum conservation equation and plug in the expressions for the momentums in terms of the energy and rest mas8, expressing one of the energies in terms of the two others. Without too much effort, you get a linear equation for one of the unknown energies in terms of all the rest masses. Then you can use that to find the kinetic energy.) II. Short Answer Section (ach answer is just a word or a phrase): A) What is the force mediator (or carrier) for the electromagnetic force? B) Do photons exert any force on other photons? (This is the easn why electromagnetic waves simply add.) C) What are the force mediators (or carriers) for the strong force? do hey exert a force on each other? D) Are strong force mediators all the same? What distinguishes them? E) When nucleii with more than 100 nucleons (i.e. protons neutrons) undergo nuclear fission or decay i.e split into small nucleii, which rest mass is bigger, the one of the original nucleus or the sum of the rest masses of the products? F) When a neutron decays into a proton plus an electron plus a neutrino, what is the process that occurs on the level of quarks? G) What is halflife? H) How does high energy radiation (e.g. x-rays, γ rays) cause dammage to living tissue? I) What process generates the energy of our Sun? J) The electron, the muon, and the tau all have same electric charge and the same isospin charge. What is different between them?
