1. In a particular nuclear fission process a Uranium-235 nucleus captures a neutron and then splits into a Lead-212 nucleus and another daughter nucleus as well as releasing 4 free neutrons. What is the other daughter nucleus that is produced in this fission reaction? a. Neon-20 b. Neon-19 c. Neon-18 d. Neon-21 e. Neon-22 2. Look up the atomic mass for Uranium-235, Lead-212, and the correct Neon isotope and then calculate the mass per nucleon for each one. Which nucleus...

A helium atom has a rest mass of mHe=4.002603u. When disassembled into its constituent particles (2 protons, 2 neutrons, 2 electrons), the well-separated individual particles have the following masses: mp=1.007276u, mn=1.008665u, me=0.000549u. How much work is required to completely disassemble a helium atom? (Note: 1 u of mass has a rest energy of 931.49 MeV.)

A helium nucleus (called an alpha particle) contains 2 neutrons and 2 protons with no electrons. If any electrons are added, there is a negligible amount of mass added but obviously one negative charge per electron is added. Three particles are injected into a constant B-field of 2T at a velocity of 3×106ms. The first particle is only the alpha particle (He++), the second particle is a nucleus with 1 electron (He+), and the third particle is a nucleus with...

The fusion of deuterium (one proton + one neutron) with tritium (one proton + two neutrons) to form a Helium nucleus (two protons + two neutrons) and one spare neutron releases about 17 MeV of energy. ( 1 eV = 1.6 x 10-19 Joules). Given that the Sun produces about 380 x 1026 Watts of luminous energy, what is the total mass of deuterium and tritium that must be fusing each second to provide this energy output? If we could...

In the movie, The Avengers, Loki's scepter contained one of the six infinity stones - the Mind Stone. Although the Mind Stone appears blue while in the scepter, it actually emits light in the yellow part of the visible spectrum, as well as low-energy gamma rays. It was these gamma rays that allowed Dr. Banner to track Loki back to New York City, where the movie?s epic final battle took place. Presumably, the Mind Stone was formed at the beginning...

The H+2 ion is composed of two protons, each of charge +e=1.60×10-19 C, and an electron (charge of electron, −e) with mass 9.11×10-31kg.The distance between the protons is 1.07×10-10m. The two protons and the electron may be treated as point charges. A-)Consider the electron is placed at the point midway between the two protons. What is the potential energy of the interaction between the electron and the two protons? (Do not include the potential energy due to the interaction between...

Instructions: Choose 8 of the 10 problems below. Show your work in detail. Answer the questions directly in this template. Before doing this, it is highly recommending that you thoroughly review the three examples in the Unit Lesson. Consider two stable isotopes, helium-3 and helium-4. How many neutrons and protons are there in each isotope? What are the mass numbers? Hint: Do not confuse mass number with atomic mass. Review the definition of them. If two protons and two neutrons...

A force ?(?) = −5.0?2+7.0? Newtons acts on a particle. a) How much work does the force do on the particle as it moves from ? = 2.0m to ? = 5.0m, in Joules? b) Find the potential energy due to this force, at position x = 2, in Joules, by finding the potential energy as a function of x, U(x). You should use the reference point of the potential energy being 0 when x = 0. c) Using either...
