You leave your love to find a new home for humanity by taking a rocket to explore the universe. therocket uses solar and nuclear fission energy sources. you are both 30 years old when you depart. youreturn 80 years younger than your love at 41 years old. the nuclear fuel has 92 protons and 143neutrons with a mass of 4.3857876e-25kg, which is hit by one neutron to cause a fission to occur. thesolar panel has a work function of 821.428571428571ev.1. how fast was your ship travelling on this journey in terms of the speed of light? 2. while your rocket was moving at this speed, what is the ratio of the length of the rocket relativeto earth compared to the length of the rocket relative to you on the rocket? 3. the tip of your rocket releases a spent nuclear fuel canister in the direction of motion at 0.75c. what is the fuel canister's velocity as observed by your love in terms of the speed of light? 4. if a nuclear fuel cannister has a mass of 156kg when you are with your love, what will its massbe the instant you are moving at 0.6c relative to your love? 5. if a photon of wavelength 0.756nm is incident on the solar panel, what will the kinetic energy ofthe ejected electron be? [ev]6. what would the wavelength of the ejected electron be if treated non-relativistically? [m]7. in each fission reaction the sum of the masses of all the particles after the reaction is equal tothe sum of all the particles used to cause the reaction. what is the energy released in eachindividual fission reaction? [j]8. what will the number of neutrons in the nuclear fuel be after beta decay? 9. what will the number of protons in the nuclear fuel be after beta decay? 10. what will the number of neutrons in the nuclear fuel be after alpha decay? 11. what will the number of protons in the nuclear fuel be after alpha decay?
