Question 2Which one of the following descriptive terms does not apply to nuclear forces?A. long-range Question 3Which one of the following processes causes the explosion of a nuclear bomb?C. chain reaction Question 4Of the reactions listed below, which will not proceed via the strong interaction?A. 2nd shortest box is correct answerQuestion 5Which one of the following statements is true concerning the proton?D. The proton is composed of two up quarks and a down quark. Question 6Which one of the following particles is not composed of quarks?muon Question 7Which one of the following names is not one that is used to name quarks?C. exotic Question 8Which one of the following statements concerning the standard cosmological model is false?The Grand Unified Theory describes the universe immediately before and shortly after the Big Bang. Question 9Note the forces: (1) weak nuclear force (3) gravitational force (2) strong nuclear force (4) electromagnetic forceThrough which force(s) can leptons interact?B. only 1, 3, and 4 Question 10Calculate the mass in GeV/c2 of a virtual carrier particle that has a range limited to 10-30 m by the Heisenberg uncertainty principle. Such a particle might be involved in the unification of the strong and electroweak forces.Answer: 98800000000000Question 11If a galaxy is 570 Mly away from us, how fast do we expect it to be moving and in what direction?Answer:11400Question 12A section of superconducting wire carries a current of 115 A and requires 1.00 L of liquid nitrogen per hour to keep it below its critical temperature. For it to be economically advantageous to use a superconducting wire, the cost of cooling the wire must be less than the cost of energy lost to heat in the wire. Assume that the cost of liquid nitrogen is $0.30 per liter, and that electric energy costs $0.10 per kW·h. What is the resistance of a normal wire that costs as much in wasted electric energy as the cost of liquid nitrogen for the superconductor?Answer:0.227Question 13Because of energy loss due to synchrotron radiation in the LHC at CERN, only 5.00 MeV is added to the energy of each proton during each revolution around the main ring. How many revolutions are needed to produce 6.00 TeV (6000 GeV) protons, if they are injected with an initial energy of 7.00
