What are the subdetectors of the Compact Muon Solenoid experiment? Briefly describe them.
(a) What is the approximate force of gravity on a 70-kg person due to the Andromeda Galaxy, assuming its total mass is \(10^{13}\) that of our Sun and acts like a single mass 0.613 Mpc away? (b) What is the ratio of this force to the person's weight? Note that Andromeda is the closest large galaxy.
Using the Heisenberg uncertainly principle, determine the range of the weak force if this force is produced by the exchange of a Z boson.
A proton and an antiproton collide head-on, with each having a kinetic energy of \(7.00 \mathrm{TeV}\) (such as in the \(\mathrm{LHC}\) at CERN). How much collision energy is available, taking into account the annihilation of the two masses? (Note that this is not significantly greater than the extremely relativistic kinetic energy.)
Assuming a circular orbit for the Sun about the center of the Milky Way Galaxy, calculate its orbital speed using the following information: The mass of the galaxy is equivalent to a single mass \(1.5 \times 10^{11}\) times that of the Sun (or \(3 \times 10^{41}\) kg ), located 30,000 ly away.
