Earth's magnetic poles;
a. are visible from space
b. are aligned with the equator
c. are not the same as geographic poles

The mass of a muon is 207 times the electron mass; the average lifetime of muons at rest is 2.21 μs. in a certain experiment, muons moving through a laboratory are measured to have an average lifetime of 7.04 μs. for the moving muons, what are (a) β (b) k, and (c) p? the rest energy of the electron is 0.511 mev.

Could someone me find the answer to this problem.
