[19] Counting: (a) Assume that there are n different quark flavors.  Determine how many different meson combinations can be made from these flavors. (b) Still assuming that there are n different quark flavors, determine how many different baryon combinations can be made from these flavors. [20] Examine the following processes, and state for each one whether it is possible or impossible, according to the Standard Model.  If possible, state which interaction is responsible - strong, electromagnetic, or weak.  If impossible, cite a conservation law that prevents the interaction from occurring. proton + antiproton  ™  p+  +  p0 h  ™  g + g S0 ™  L  +  p0 S-  ™  n  +  p- e+ + e- ™  m+  +  m- m-  ™  e-  +  electron anti-neutrino D+  ™  p  +  p0 electron anti-neutrino +  p  ™  n  +  e+ e  +  p  ™  ne  +  p0 p  +  p  ™  S+  +  n  +  K0  +  p+  +  p0
