    Your Answer: 
    A physicist working at a linear particle accelerator is studying pions (π^+, mπ = 270 me) that have an average rest lifetime of 26.0 ns. The pions move through a series of parallel plates (the linac) and into a velocity selector. After leaving the selector, the particles enter into a very long drift tube. At this point, the physicist measures the... show more
