A gamma ray from 198Au incident normally on a thick aluminum slab travels 1.45 centimeter before it undergoes a Compton scattering. Determine the range of angles through which the gamma could scatter and still have at least a 10 percent probability of re-emerging from the incident slab surface without undergoing another interaction.
Interpreting attenuation as a reflection loss calculate the lower limit to the effective reflectivity at the core cladding boundary
A flywheel comprises a uniform circular disk with a mass of 105.0 kg and a radius of 1.0 m. It rotates with an angular velocity of 1227 rev/min. What is the initial kinetic energy of the wheel
At t = 0, a particle leaves the origin with the velocity of 9 m/ s in the positively direction and moves in the x y plane with a constant acceleration of (2.0i - 4.0j) m/ s2. At the instant the x coordinate of the particle is 15m, what is the spee..
