20. The fact that we can only calculate probabilities for values of physical quantities in quantum measurements means that (A) radiation and matter are not described by mathematical relations between measurements. (B) the probabilities cannot be calculated from mathematical relationships. (C) the results of physical measurements bear no relationship to theory. (D) the average values of a large number of measurements correspond to the calculated probabilities. (E) the average of the values calculated in a large number of different theories corresponds to the results of a measurement.
19. Suppose Bohr had chosen the potential energy of the electron in the hydrogen atom to be V = 0 when the electron is in the orbit with n = 1. He could do this by (A) choosing n = 1 for the orbit where the kinetic energy of the electron is zero. (B) adding a constant 13.6 eV to the potential energy for all values of n. (C) adding a constant 27.2 eV to the potential energy for all values of n. (D) subtracting a constant 13.6 eV from the potential energy for all values of n. (E) subtracting a constant 27.2 eV from the potential energy for all values of n.
18. The number of photons per second passing a plane perpendicular to a collimated monochromatic (one frequency) beam of light transporting power P is directly proportional to (A) the wavelength of the light. (B) the frequency of the light. (C) the power of the beam. (D) all of the above. (E) only ( A ) and ( C ) above.

8. A hoop, a solid cylinder, and a solid sphere all have the same mass m and the same radius R. Each is mounted to oscillate about an axis a distance 0.5R from the center. The axis is perpendicular to the circular plane of the hoop and the cylinder and to an equatorial plane of the sphere as shown below. Which is the correct ranking in order of increasing angular frequency ω (from highest to lowest)?
7. A segment of wire carries a current of 25 A along the x axis from x = −2.0 m to x = 0, and then along the z axis from z = 0 to z = 3.0 m. In this region of space, the magnetic field is equal to 40 mT in the positive z direction. What is the magnitude of the force on this segment of wire?
6. How much energy is dissipated as heat during a two-minute time interval by a 1.5-kΩ resistor which has a constant 20-V potential difference across its leads?
