Find the value of T1 if 1 = 30°, 2 = 60°, and the weight of the object is 139.3 newtons.

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.

Many machines- including inclined planes such as ramps- increase the strength of the force put into the machine but decrease the distance over which the force is applied.

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.
