Particles called π-mesons are created by accelerator beams
Particles called π-mesons are created by accelerator beams. If these particles travel at 2.74 x 108 m/s and live 2.60 x 10-8 s when at rest relative to an observer, how long (in s) do they live as viewed in the laboratory?

Suppose a particle called a kaon is created by cosmic radiation striking the atmosphere. Randomized variables c = 0.89 c t = 1.25 times 10^-8 s It moves by you at 0.89c, and it lives 1.25 times 10^-8 s when at rest relative to an observer. How long does it live, in seconds, as you observe it? Delta t =

1. Subatomic particles called muons can be created in the upper atmosphere by collisions of cosmic rays (energetic particles coming from astrophysical sources). As we shall see in a few lectures, muons quickly decay (in 2.2 microseconds on average) into other particles. Consider a muon that was created at a height the same as the top of a nearby mountain, traveled straight down towards the Earth through the atmosphere at 0.9 times the speed of light, and then decayed at...

1) Consider an accelerator that collides beams of electrons and protons. The beams actually consist of bunches of particles, that are traveling essentially at the speed of light. For both the electron and proton beams, the bunche:s are 2 cm long (in the direction of motion) and they are circulating in rings of 300 m circumference. Each ring contains six bunches of protons (or electrons). Each bunch contains 1013 particles. Assume that the particles in the bunches are distributed uniformly...

5) In the device diagrammed below an accelerator injects a beam of positively charged ions into the evacuated space between two metal plates. The ions are assumed to be missing one electron and they all seem to leave the accelerator with the same speed. A uniform magnetic field of magnitude 0.1 T is maintained between the plates. In separate experiments beams of ions are injected into the space between the plates . In the first experiment the beam of ions...
