3. Canadian nuclear reactors use heavy water moderators in which elastic collisionsoccur between the neutrons and deuterons of mass 2.0 × my, where my is themass of a neutron.a. What is the speed of a neutron, expressed as a fraction of its original speed,after a head-on, elastic collision with a deuteron that is initially at rest?b. What is its kinetic energy, expressed as a fraction of its original kineticenergy?c. How many such successive collisions will reduce the speed of a neutron to1/59,000 of its original value?

A "mad" scientist attempts to take a sample of Mercury-199 and bombard it with neutrons. The reaction creates a proton and Gold-199. His joy is short-lived when in a few days the radioactive Gold-199 reverts back to Mercury-199 emitting a single particle. What is the emitted particle? 199 79 O O → 199 80Hg+? a beta (-) particle ß- a proton; H+ an alpha particle; a a neutron; nº
