Answer options

  1. increases
  2. remains the same
  3. decreases
  4. becomes zero

Correct answer and explanation

Correct answer: decreases

Explanation: āœ… Correct Answer: C. decreases šŸ“š Explanation: When a person on a swing stands up, their center of gravity rises, which effectively shortens the length of the pendulum. According to physics, a shorter length leads to a faster oscillation. Therefore, the 'time period' (the time taken for one full swing) decreases. This makes the person swing back and forth more quickly than when they were sitting.
