A rubber string is tied to a nail on the wall. The rubber string is pulled gently to stretch slightly. Which of the following phenomena may occur after the release of the string?
- A. Sound is produced
- B. Rubber string moves up and down
- C. The quality of sound changes with the tension of the string
- D. All the above happen
Step-by-step solution
When the rubber string is pulled and released, it vibrates, producing sound (A) and moving up and down (B). The tension in the string influences the frequency and hence the quality (pitch) of the sound (C). Therefore, all three phenomena can occur after release.
