A plucked guitar string repeats the same vibration over and over. Such motion is called:

  1. Periodic
  2. Parabolic
  3. Panoramic
  4. Piecemeal
Show answer and solution

Correct answer: A. Periodic

1. Each vibration takes the same time as the one before. 2. The motion repeats itself at regular intervals. 3. That motion is periodic. _Source: OpenStax College Physics 2e, Chapter 16, Oscillatory Motion and Waves._

The SI unit for frequency, meaning one cycle per second, is the:

  1. Hexad
  2. Hertz
  3. Henry
  4. Hydra
Show answer and solution

Correct answer: B. Hertz

1. Frequency counts cycles completed in a second. 2. One cycle per second defines the unit. 3. That unit is the hertz. _Source: OpenStax College Physics 2e, Chapter 16, Oscillatory Motion and Waves._
