In the following fusion reaction, a deuteron and a Hydrogen-3 atom (Tritium) yields one Helium-4 atom, 1 neutron, and some released energy. Determine the amount of released energy (in MeV, to one decimal place). All relevant masses are on your radioisotope data handout. Deuterium Helium Fusion + Energy Tritium Neutron A/ Question 20 (5 points) An unstable actinium (AC-227) atom spontaneously emits an alpha particle and transmutes into an atom of some other element. a) Show the process in a reaction notation b) What is the new element? c) Determine the energy released in reaction.Question 15 (3 points) A person flying in a spaceship at 0.96c measures 65 seconds on her watch (in the ship). You are watching them fly by you, what time do you measure (to the nearest second) ? Your Answer: Answer units Question 16 (3 points) Mr. Smith is about 75cm wide. He somehow manages to accelerate himself to a certain speed. An observer watching him pass observes that he is 55cm wide. Determine Mr. Smith's speed. Enter your speed as a percentage of the speed of light. For example, for a speed of 0.941c, enter 0.941. Your Answer: Answer Question 17 (2 points) A proton (my=1.67x10"-kg) moves with a speed of 0.Sc through a laboratory. What is the relativistic kinetic energy (in ]) of the proton in the laboratory frame? Question 18 (3 points) Determine the binding energy of Phosphorous-32 (to the nearest MeV). Show all of your work
