PHY 114: Absorption of Nuclear Radiation Abstract: The purpose of this experiment was to determine the mass thickness attenuation factor for beta rays when they pass through polyethylene sheets of varying thicknesses. This was done by using an apparatus that measured the seven different intensities and then taking these values‚ putting them through a number of calculations and finally generating a graph of ln(I_corr) versus the thickness of the polyethylene sheets. Once this graph

ello Doc Al and others. I am progressing along with my on-line basic physics course. I completed a new module and have some assessment questions to answer. Please review and let me know the ones that are correct. Those that are wrong just a little clue as to where my thinking process went a stray. I will add my thought process to the ones that I missed telling how I came up with the answer that I did. Thanks for taking the time to assist me on some basic questions. 1. What is the rotational speed
