as per attached questions, please explain the derivations process for me. thank you
constants and the mass of the electron
what would be the physical consequences if the mass of the electron was twice the observed value?
Macroscopic Scattering Cross Section
Find the macroscopic scattering cross section of U02, assuming a density of 10 g/cm^3 (=10 000 kg/m^3) and σs(U) is approximately equal to 8.9 b and σs(0) is approximately equal to 3.75 b (10^-28 m^2).
Consider a point source emitting 10^12 neutrons/s in a vacuum. Calculate the flux and the current at a distance of 1 m from the source.
Calculate the mean free path of 1 eV neutrons in graphite. The total cross section of carbon at this energy is 4.8 b. Show steps to solution.
Beams of Monoenergetic Neutrons
Two beams of monoenergetic neutrons with energy equal 1eV intersect at an angle of 90ยบ. The density of neutrons in both beams is 2x10^8n/cm3. a)Calculate the intensity (current) of each beam. b)Calculate the neutron flux where the two beams intersect. c)Calculate the neutron current where the two beams intersect.
Two monoenergetic neutron beams of intensities I1=2x10^10 n/cm^2/s and I2=1x10^10 n/cm^2/s intersect at an angle of 30 degrees. Calculate the neutron flux and current at the point where they intersect.
Email me for Clarification. I only need Parts C and D... I solved A and B, the answers are below. Not too much work left for 25 credits. Your help is appreciated. The only radiogenic lead isotope that is not either stable (Pb-206, 207, 208) or with a halflife of less than one day is Pb-210, which is found in nature in sec ...continues
