In the context of simple harmonic motion, the correct answer is:
B. The motion of a rotating beacon
Explanation:
- Simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement and acts in the opposite direction of that displacement.
- The motion of a rotating beacon can be considered an example of simple harmonic motion because it follows a periodic back-and-forth movement that can be described in terms of a sine or cosine function.
- As the rotating beacon moves back and forth in a repetitive manner, it exhibits characteristics of simple harmonic motion due to its oscillatory nature.
