11.7 mph to m/s 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 235u isotopes. calculate the wavelength (in nm) associated with a beam of neutrons moving at 6.90 × 102 m/s (mass of a neutron = 1.675 × 10−27 kg). enter your answer in scientific notation.
