What minimum speed must each particle have when they are 100 fm apart in order to end up far from each other? (Recall that 1 fm = 10-15 m.)

- You have a machine that produces a beam of π(pi) mesons moving at a speed of 0.9938c. In your lab, you aim this beam at a target that is 278.70 m away from your machine. The half‑life for π(pi) meson decays is 26.0 ns. Calculate the time it takes in ns, in the lab frame, for particles to travel from your machine to the target. Find the classically expected fraction of particles that would reach the target without having decayed. Find the time it takes, in the rest frame of the particles, for a particle to travel from the machine to the target.arrow_forwardAn electron and a positron (an antielectron) make ahead-on collision, each moving at v = 0.99999c. In thecollision, the electrons disappear and are replaced by twomuons (mc2 = 105.7 MeV), which move off in oppositedirections. What is the kinetic energy of each of themuons?arrow_forwardA positive K meson (K+) is an unstable subatomic particle that decays into other particles. At rest, its mean lifetime is 1.23 x 10-8 s. (a) What do you measure the mean lifetime of a K+ to be if it is moving at 0.800c relative to you? (b) As measured from the reference frame of this K+, what is the mean lifetime of a second K+ that is at rest relative to you?arrow_forward
- A pion is an unstable sub-atomic particle commonly produced in high-energy physics experiments. What is the speed of a pion if its average lifetime is measured to be 44.0 ns? At rest, its average lifetime is 26.0 ns.arrow_forwardA positive K meson (K+) is an unstable subatomic particle that decays into other particles. At rest, its mean lifetime is 1.23 * 10-8 s. (a) What do you measure the mean lifetime of a K+ to be if it is moving at 0.800c relative to you? (b) As measured from the reference frame of this K+, what is the mean lifetime of a second K+ that is at rest relative to you?arrow_forwardA charged pion & (π‡), an unstable particle of mass 140 MeV/c², is known to decay into a muon (μ‡, mass 106 MeV/c²) and a neutrino (1; we can treat it as massless here). In this decay of pion (→ + ₁), typically only the muon is detected, the neutrino being an electrically neutral particle that rarely interact with other matter. Properties of neutrinos in this decay are inferred from measured properties of pion and muon. Explain, as conceptually as possible, why it is not possible for a pion to simply decay into a muon, without an associated neutrino. That is, why is this decay, π → Mt, impossible? (Note: If you happen to know about lepton numbers and neutrino flavors, please give an explanation that does not make use of concepts we have not yet covered.)arrow_forward
- The K+ meson, a subatomic particle, has an average rest lifetime of 1.0 x 10-8 s. If the particle travels through the laboratory at 2.6 x 108 m/s, by how much has its lifetime, relative to the laboratory, increased?arrow_forwardPleas help with part (b), I already try with the answer of 7.46*10^-7 but is incorrect.arrow_forwardTwo particles in a high-energy accelerator experiment are approaching each other head-on, each with a speed of 0.9300c as measured in the laboratory.

- 5.3 A spaceship moves with speed V relative to an observer O, on a straight line which passes very near the observer. A source on the spaceship emits light of wavelength 2o = 500 nm in the frame of reference of the spaceship. For what range of the spaceship's speed will the light be visible to the observer? The wavelengths of visible light stretches from 2A = 400 nm to ig = 700 nm, approximately. Ans.: -0.22 < Bß<0.33arrow_forwardA linear particle accelerator using beta particles collides electrons with their anti-matter counterparts, positrons. The accelerated electron hits the stationary positron with a velocity of 98 x 106 m/s, causing the two particles to annihilate.If two gamma photons are created as a result, calculate the energy of each of these two photons, giving your answer in MeV (mega electron volts), accurate to 1 decimal place. Take the mass of the electron to be 5.486 x 10-4 u, or 9.109 x 10-31 kg.Note: Assume that the kinetic energy is also converted into the gamma rays, and is included in the two photons.arrow_forwardThe muon is an unstable particle that spontaneously decays into an electron and two neutrinos. If the number of muons at t = 0 is N0, the number at time t is given by , where τ is the mean lifetime, equal to 2.2 μs. Suppose the muons move at a speed of 0.95c and there are 5.0 × 104 muons at t = 0. (a) What is the observed lifetime of the muons? (b) How many muons remain after traveling a distance of 3.0 km?arrow_forward
