Decreases
Increases
Becomes infinite
Does not change
Answer is Right!
Answer is Wrong!
The correct answer is: A. Decreases.
When a person sitting on a swing stands up, their center of mass is raised. This means that the swing has to move further to reach the same point in its oscillation. This increases the time it takes for the swing to complete one oscillation, which is the definition of frequency.
Here is a more detailed explanation of each option:
- Option A: Decreases. When a person sitting on a swing stands up, their center of mass is raised. This means that the swing has to move further to reach the same point in its oscillation. This increases the time it takes for the swing to complete one oscillation, which is the definition of frequency.
- Option B: Increases. This is incorrect because the frequency of oscillation decreases when a person stands up on a swing.
- Option C: Becomes infinite. This is incorrect because the frequency of oscillation cannot become infinite.
- Option D: Does not change. This is incorrect because the frequency of oscillation does change when a person stands up on a swing.
