Question

g Observer A, who is at rest in the laboratory, is studying a particle that is moving through the laboratory at a speed of 0.624c and determines its lifetime to be 159 ns. (a) Observer A places markers in the laboratory at the locations where the particle is produced and where it decays. How far apart are those markers in the laboratory

Answer 1

`D=29.7648m`

Step-by-step explanation:

From the question we are told that

Speed of the particle
`V=0.624c`

Lifetime
`t=159ns`

Generally the equation for distance is mathematically given by

`D=Vt`

`D=0.624c*159*10^-^9`

`D=0.624*3*10^8*159*10^-^9`

`D=29.7648m`

Therefore the markers are
`D=29.7648m` apart
