description: "The following are multiple choice questions (with answers) about high\
  \ school physics.\n\nQ: A microwave oven is connected to an outlet, 120 V, and draws\
  \ a current of 2 amps. At what rate is energy being used by the microwave oven?\n\
  (A) 10 W (B) 30 W (C) 60 W (D) 240 W\nA: Let's think step by step. Rate of energy\
  \ usage is known as power; in an dissipative electrical circuit, power is given\
  \ by voltage times current. So in our case, the power is 120 V times 2 amps, or\
  \ 240 W. The answer is (D).\n\nQ: A point charge, Q = +1 mC, is fixed at the origin.\
  \ How much work is required to move a charge, Q = +8 \xB5C, from the point (0, 4\
  \ meters) to the point (3 meters, 0)?\n(A) 3.5 J (B) 6.0 J (C) 22.5 J (D) 40 J\n\
  A: Let's think step by step. To calculate the work required to move a charge from\
  \ one location to another in a fixed electric field, it is enough to calculate the\
  \ potential difference between the two locations. Here, the potential only depends\
  \ on the distance between the charges; it\u2019s $k q_1 q_2 / r$, where $k$ is Coulomb\u2019\
  s constant. Plugging in values $q_1 = $ 1 mC, $q_2 = 8 \\mu$ C, gives the answer\
  \ as 5.992 J, which rounds to 6 J. The answer is (B).\n\nQ: Which of the following\
  \ conditions will ensure that angular momentum is conserved? I. Conservation of\
  \ linear momentum II. Zero net external force III. Zero net external torque\n(A)\
  \ I and II only (B) I and III only (C) II and III only (D) III only\nA: Let's think\
  \ step by step. Torque is defined as the change in angular momentum; if there is\
  \ zero external torque, angular momentum is conserved. The answer is (D).\n\nQ:\
  \ A photocell of work function \u03D5 = 2eV is connected to a resistor in series.\
  \ Light of frequency f = 1 \xD7 10^15 Hz hits a metal plate of the photocell. If\
  \ the power of the light is P = 100 W, what is the current through the resistor?\n\
  (A) 2:00 AM (B) 6:00 AM (C) 12:00 AM (D) 24 A\nA: Let's think step by step. The\
  \ only answer above which has units of current is D, 24 A. The answer is (D).\n\n\
  Q: A pipe full of air is closed at one end. A standing wave is produced in the pipe,\
  \ causing the pipe to sound a note. Which of the following is a correct statement\
  \ about the wave\u2019s properties at the closed end of the pipe?\n(A) The pressure\
  \ is at a node, but the particle displacement is at an antinode. (B) The pressure\
  \ is at an antinode, but the particle displacement is at a node. (C) The pressure\
  \ and the particle displacement are both at nodes. (D) The pressure and the particle\
  \ displacement are both at antinodes.\nA: Let's think step by step. At the closed\
  \ end of the pipe, the particles cannot have any net displacement because the pipe\
  \ closure stops them. So the particle displacement is at a node. This closure also\
  \ causes the pressure to be maximal, i.e. an antinode. The answer is (B)."
