An unstable particle produced in an accelerator experiment travels at constant velocity, covering 1.00 m in 3.44 ns in the lab frame before changing ("decaying") into other particles. in the rest frame of the particle determine how long it lived before decaying?

Explanation:

= Distance covered = 1 m

= Time taken = 3.44 ns

c = Speed of light =

Velocity would be

Time in rest frame is given by

It lived before decaying

it about 600 mph from what i calculated

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
