28.64. Set Up: and so Solve: 28.65. Set Up: Solve: is very small, so no, we do not need to be concerned with the wave nature. 28.66. Set Up: The energy added to mass m of the blood to heat it to and to vaporize it is with and The energy of one photon is Solve: (a) The pulse must deliver 5.07 mJ of energy. (b) (c) One photon has energy The number N of photons per pulse is the energy per pulse divided by the energy of one photon: 28.67. Set Up: Solve: Take the minimum uncertainty product, so Reflect: Uncertainty in energy of the photon corresponds to a spread in the wavelength of the photon emitted in the transition. 28.68. Set Up: Let the xy plane be horizontal and let the ball be thrown in the x direction. Take the minimum uncertainty product, so Let be the length of one side of the cubical volume, so Solve: (a) (b) It takes the ball to travel from one student to the other. During 10 s the uncertainty in introduces an uncertainty of in the y component of the position of the ball. 1 1.0 m / s 21 10 s 2 5 10 m v y D v y 5 D p y m 5 0.1 kg # m / s 0.10 kg 5 1.0 m / s. 50 m 5.0 m / s 5 10 s D p y 5 0.0663 J # s 2 p 1 0.10 m 2 5 0.1 kg # m / s 10 cm 5 0.10 m.

### What students are saying

• 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.

Kiran Temple University Fox School of Business ‘17, Course Hero Intern

• 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.

Dana University of Pennsylvania ‘17, Course Hero Intern

• 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.
