PROBLEM 5A: (4pts) Two pieces of tape are stuck to the table. They each get ripped off and the brought close to one another (without touching). What happens? (A) They are attracted by one another (B) Nothing (C) They are repelled by one another (D) Cannot be determined Explain your reasoning. PROBLEM 5B: (6pts) Consider the RC circuit shown. Which of the following S must go to zero after a long time? Assume the switch is opened/closed a long time before closing/opening. (Circle all that apply) - R (A) Charge on C when S is closed (B) Current to C when S is closed (C) Voltage across C when S is closed (D) Charge on C when S is open (E) Current to C when S is open (F) Voltage across C when S is open PROBLEM 5C: (8 pts) The A-string on a guitar is typically tuned to a frequency of 110 Hz. While tuning you're A-string against a digital tuner, you can tell your string's pitch is a bit flat (i.e. frequency is too low). As a result, you hear beats at a frequency of 3 Hz. What is the frequency your guitar string is producing? f = PROBLEM 5D: When observing the Andromeda Galaxy, astrophysicists see light with frequency 4.571 x 1014 Hz. They know that at rest this source has an actual frequency of 4.566 x 1014 Hz. Assume that the Earth is stationary (i.e. vo = 0). (A) (4 pts) Is the Andromeda Galaxy moving toward us or away from us? Explain. (B) (10 pts) Calculate the speed at which Andromeda Galaxy moving toward us or away from us. Be careful not to round too early
