Question

consider the three statements. two are true. one is false. select the false statement. tap a statement to select or deselect. tap the check answer button when ready. #1 the frequency of a vibrating object refers to the number of complete cycles of vibrations made per unit of time. #2 the frequency of a vibrating object refers to the average speed with which the object moves over the course of a vibration. #3 the frequency of a vibrating object refers to how often a vibrating object repeats its vibration.

Explanation:

• Statement #1 correctly defines frequency as the number of full vibration cycles per unit time.
• Statement #3 correctly describes frequency as how often a vibration repeats, which aligns with the core definition of frequency.
• Statement #2 incorrectly equates frequency to the average speed of the vibrating object; frequency has no direct relation to the object's movement speed, only the rate of vibration repetition.

Answer:

#2. The frequency of a vibrating object refers to the average speed with which the object moves over the course of a vibration.
