Particle track detectors are used to measure the speed of particles if the lifetime of the particle is known. Particle X has a lifetime of 256.2 ps. These particles are created in an experiment inside the detector by a given reaction. The particles leave 20.1 cm long tracks on average before they decay into other particles not observable by the detector. What is the average speed of the particles in terms of the speed of light?
Particle physiclsts use particle track detectors to determine the lifetime of short-llved particles. A muon has a mean llfetlme of 2.2 us and makes a track 7.8 cm long before decaying Into an electron and two neutrinos. What was the speed of the muon? 0.00118
The length of a particles track from the position it was produced until its decay in a scattering chamber is measured to be 2.12 cm. The speed of this particles is 0.97c. Find the γ-factor: γ= Find the lifetime of that particle inferred by stationary observers: t= ____________ seconds Find the proper lifetime of that particle: t0= ____________ seconds
A certain type of elementary particle travels at a speed of 2.80x108 m/s At this speed, the average lifetime is measured to be 3.86x10-6 s Part A What is the particle's lifetime at rest? nVα ΑΣφ ? Ato = Request Answer Submit Provide Feedback
An unstable high-energy particle is created in the laboratory, and it moves at a speed of 0.994c. Relative to a stationary reference frame fixed to the laboratory, the particle travels a distance of 1.84 × 10-3 m before disintegrating. What is (a) the proper distance and (b) the distance measured by a hypothetical person traveling with the particle? Determine the particle's (c) proper lifetime and (d) its dilated lifetime. Numerical answer is not important...a) I do not understand why 1.84...
