Integrated Concepts Suppose you are designing a proton decay experiment and you can detect 50 percent of the proton decays in a tank of water. (a) How many kilograms of water would you need to see one decay per month, assuming a lifetime of 1031 y? (b) How many cubic meters of water is this? (c) If the actual lifetime is 1033 y, how long would you have to wait on an average to see a single proton decay?
Integrated Concepts Assuming conservation of momentum, what is the energy of each (ray produced in the decay of a neutral at rest pion, in the reaction +?
Why can’t either set of quarks shown below form hadron?
The detail that you can observe using a probe is limited by its wavelength, Calculate the energy of a particle that has a wavelength of 11016 m, small enough to detect details about one-tenth the size of a nucleon.
In general, how do we determine if a particle reaction or decay occurs?
Is the decay possible considering the appropriate conservation laws? State why or why not.
. If the average lifetime of a proton was 1033 years, about how many protons would you have to assemble together and observe simultaneously to witness a total of 100 proton decays in one year? Explain the reasoning that led to your conclusion.
The intensity of cosmic ray radiation decreases rapidly with increasing energy, but there are occasionally extremely energetic cosmic rays that create a shower of radiation from all the particles they create by striking a nucleus in the atmosphere. Suppose a cosmic ray particle having an energy of 1010 GeV converts its energy into panicles with masses averaging 200MeV/c2. (a) How many particles are created? (b) If the particles rain down on a 1.00-km2 area, how many particles are there per square meter?
What are six particle conservation laws? Briefly describe them.

Is the decay possible considering the appropriate conservation laws? State why or why not.
Another set of reactions that fuses hydrogen into helium in the Sun and especially in hotter stars is called die CNO cycle: 12C+1H13N+ 13N13C+e++ve 13C+1H14N+ 14N+1H15O+ 15O15N+e++ve 15N+1H12C+4He This process is a “cycle” because 12Cappears at the beginning and end of these reactions. Write down the overall effect of this cycle (as done for die proton-proton chain in 2e+41H4He+2ve+6 . Assume that the positrons annihilate elections to form more rays.
