Obtain how many of the particles remain in beam

Reference no: EM13679481

Particles with a proper half-life of 1.92 x 10^-6 second travel a straight line distance of 500 meter at a constant speed of 2.6 x 10⁸ meter per second. The initial beam contains 1.20 x 10¹⁴ particles. Obtain how many of the particles remain in beam, measure by the lab observer, as they hit the target?
