A muon is a type of unstable subatomic particle. When high-speed particles from outer space (sometimes called "cosmic rays") collide with atoms in the upper atmosphere, they can create muons which travel toward the Earth. Suppose a muon created in the atmosphere travels at a speed of 0.941c toward the Earth's surface for a distance of 3.48 km, as measured by a stationary observer on Earth, before decaying into other particles. (a) As measured by the stationary observer on Earth,...

PHW 21 due at Class 24 A particle accelerator is a device designed to create high-energy particles for collision experiments. In one such accelerator, protons that are initially at rest are accelerated through a net electrical potential ? to a total relativistic energy ? = 6.5 GeV. The accelerator itself is a large circular ring with a radius ? = 1.1 km. For these protons, calculate the following: (a) The net accelerating potential, ?. (b) Their momentum, in MeV/c. (c)...

3. (10 pts) Heisenberg Uncertainty Principle The uncertainty principle places a limit on specifying the location and momentum of a particle simultaneously. Δ?Δ? ≥ ℏ/2 This is a consequence of the wave nature of particles, which we can see by examining the uncertainty in the single-slit diffraction of light. (a) In single-slit diffraction, the width of the slit ? represents the uncertainty in x position of the beam, ∆?: ∆? = ? We can imagine that we can try to...
