Muons are unstable subatomic particles that decay to electrons with a mean lifetime of 2.2 μs . They are produced when cosmic rays bombard the upper atmosphere about 12.4 km above the earth's surface, and they travel very close to the speed of light. The problem we want to address is why we see any of them at the earth's surface. a) What is the greatest distance a muon could travel during its 2.2 μs lifetime? b) According to your...

Muons are unstable subatomic particles that decay to electrons with a mean lifetime of 2.2 μs . They are produced when cosmic rays bombard the upper atmosphere about 10.9 km above the earth's surface, and they travel very close to the speed of light. The problem we want to address is why we see any of them at the earth's surface. 1. From the point of view of the muon, it still lives for only 2.2 μs , so how...

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?

Review The Pi Meson An elementary particle called a pi meson (or pion for short) has an average lifetime of 2.6 x 108 s when at rest. Part A Suppose a pion moves with a speed of 0.92 c relative to a stationary laboratory. If there were NO RELATIVISTIC effects, how far would the pion travel in the laboratory before decaying.

The weight of each head of lettuce was then recorded. The mean weight was 2.2 pounds with a standard deviation of 0.1 pounds. The population standard deviation is known to be 0.2 pounds. Construct a 95 % confidence interval for the population mean welght of the heads of lettuce. State the confidence...
