30.47. Set Up: The energy released is the energy equivalent of the mass decrease. From Table 30.4, the has mass and the has mass Solve: The mass decrease is and the energy equivalent is 105.2 MeV. 30.48. Set Up: p and n have baryon number and has baryon number and all have baryon number zero. Baryon number is conserved if the total baryon number of the products equals the total baryon number of the reactants. Solve: (a) reactants: Products: Not conserved. (b) reactants: Products: Not conserved. (c) reactants: Products: Conserved. (d) reactants: Products: Conserved. 30.49. Set Up: Section 30.9 says the strong interaction is 100 times as strong as the electromagnetic interaction and that the weak interaction is times as strong as the strong interaction. The Coulomb force is and the gravitational force is Solve: (a) (b) (c) (d) Reflect: The gravity force is much weaker than any of the other three forces. Gravity is important only when one very massive object is involved.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
