Question 3 of 30) value: 4.00 points 2 attempts left Check my work Be sure to answer all parts. Report Thermal neutrons are neutrons that move at speeds comparable to those of air molecules at room temperature. These neutrons are most effective in initiating a nuclear chain reaction among isotopes. Calculate the wavelength (in nm) associated with a beam of neutrons moving at 6.93 x 10 m/s (mass of a neutron = 1.675 x 10-27 kg). Enter your answer in...
