An exotic particle with a half life of 223.93microseconds, according to clocks with no relative motion, is observed to travel through the atmosphere (with a thickness of about 500 km from the surface of the Earth). The particles are found to be moving at speed 0.999 c when detected on the surface of the Earth. These particles are known to be produced at the top of the atmosphere. Despite (half life=223.93microseconds) times the speed of particles being less than the thickness of the atmosphere, scientists find that less than half of the exotic particles have decayed after traveling through the atmosphere. Explain this? (You must answer in one or two sentences!)

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...
1) Muons naturally decay with a half-life of 1.52 μs, meaning that if Mo muons are created at t'=0, then vo will survive at time t 1.52 us as measured by their 'internal clock'. The population N actually decays exponentially according to N(t')=Mo exp(-t σ), where σ=2.2,s. Assume that muons are created in a laboratory and accelerated to essentially the speed of light (a wee bit slower, of course!) in a time much shorter than their half-life. The muons then...
Please show any steps and relevant explanation that might help.
Also please be legible. I will rate :) Thanks!
Question 4 our atmosphere, making extensive showers of secondary particles that can be measured in detectors which observe the ionization they create as they descend through our atmosphere. Most cosmic rays are protons photons. But a few years ago a puzzling phenomenon was observed: type" appeared to be coming from a bizarre deep space object known as Cygnus X3. The reason...
Problem 1 chemists to determine the composition of a sample. Let's explore one type of mass spectrometer, which uses electric and magnetic fields. For each step below, sketch a diagram to help you with the analysis Mass spectrometers, which separate ions based on mass, are often used by a. In Step 1 of mass spectrometry, an accelerator releases a charged particle from rest near one plate of a charged parallel-plate capacitor, so that the particle accelerates toward the other plate...

1. A vacuum bubble forms in a liquid and subsequently collapses. The liquid has density 1g em 3 and pressure equal to 1 standard atmosphere. The initial radius of the bubble is 2 mm. Using dimensional analysis, estimate the duration of the collapse. 2. An astronaut throws a small rock whilst standing on an open plain on Mars. Their hand is moving at approximately 60 km h -...
