In 2001 the National Opinion Research Center reported on the National Gun Policy Survey. The results of the survey include information about U.S. adults' opinions of government regulation of firearms. To obtain a random sample of adults in the United States, 1,200 participating households were identified through random digit dialing and then the adult with the most recent birthday (rather than the person who answered the phone) was interviewed. Of those who were interviewed, 78% favored requiring background checks for gun sales between individuals. Which of the following best describes the population of interest in the National Gun Policy Survey? Adults with phone numbers. All adults in the United States Adults in each household with the most recent birthday 1,200 U.S. adults 78% who favored requiring background checks for gun sales between individuals

Which of the following is TRUE about immigrant workers in the United States? Most immigrants to the United States prosper within a few years of arriving here. Most immigrant workers earn more than minimum wage and also receive some benefits. About 5 percent of U.S. restaurant workers in the United States are people born abroad. Immigrants do the jobs that no one else wants.

61. The Earthquake wave is an example of spherical wave. The energy is emitted at the epicenter of the Earthquake (origin) at a rate ($P_a$) of 100 Joules per second. The intensity (I) of the wave at 5.0 km from the epicenter is, A. $2.4 \times 10^{-9} W/m^2$ B. $9.6 \times 10^{-9} W/m^2$ C. $4.8 \times 10^{-9} W/m^2$ D. $3.0 \times 10^{-9} W/m^2$ Hint: interpret correctly what is 5 km and do the necessary unit conversion. 62. Transverse waves on a string have wave speed 6.0 m/s, amplitude 0.050 m, and wavelength 0.520 m. These waves travel in the $+x$ direction, and at $t = 0$ the $x = 0$ end of the string is at $y = 0$ and moving upward. The equation of the wave is, A. $y_o = (0.050 m) \sin(72t - 12x)$ B. $y_o = (0.050 m) \sin(72t + 12x)$ C. $y_o = (0.050 m) \sin(12t + 72x)$ D. $y_o = (0.050 m) \sin(12t - 72x)$ CHAPTER 13 MECHANICS OF FLUID 63. You hold a piece of wood in one hand and a piece of iron in the other. The volume of the piece of wood is five times as greater as the volume of the piece of iron, and you hold them fully under water at the same depth. At the moment you let go of them, which one experiences the greater buoyancy force? Given $\rho_{iron} = 7.9 g/cm^3$, $\rho_{wood} = 0.6 g/cm^3$, $\rho_{water} = 1.0 g/cm^3$ A. The piece of wood. B. The piece of iron. C. They experience the same buoyancy force. D. More information is needed.
2. Argand Diagrams for Current and Charge The current in a circuit is represented by the complex number $I(t) = I_0e^{i(\omega t + \phi)}$. Current cannot be complex, but we represent it this way with the understanding that the real part will represent the actual current in the circuit. 1. Represent the current, $I$ on an Argand diagram at $t = 0$ and with your choice of $\phi$. 2. Represent $\dot{I}$ on the same diagram at $t = 0$ and with the same choice of $\phi$. What is the phase of $I$ relative to $\dot{I}$ at any time? 3. Represent the charge $q$ flowing in the circuit on the same diagram at $t = 0$ and the same choice of $\phi$. What is the phase of $I$ relative to $q(t)$ at any time?
