A pion is an unstable particle that has a mean lifetime of 2.55 × 10^-8 s.This is the time interval between its creation in a nuclear process and its extinction into decay products,as measured in a frame of reference at rest with respect to the pion.An average pion is traveling at 0.230c relative to Earth.How far does it travel in its lifetime,relative to Earth? A)2.07 m B)1.81 m C)2.23 m D)3.22 m E)3.50 m

The distance traveled by the pion relative to Earth is calculated using the formula: distance = velocity × time. The velocity is 0.230c, and the time is the mean lifetime of the pion, 2.55 × 10^-8 s. Therefore, the distance is 0.230 × 3 × 10^8 m/s × 2.55 × 10^-8 s = 1.81 m.
