Two spherical objects have masses of 8.1 x 103 kg and 6.4 x 106 kg. The gravitational attraction between them is 125 N. How far apart are their centers?

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.
