The period of a pendulum is measured to be 3.0 s in the inertial frame of the pendulum. Find the period by an observer moving at 0.95 C with respect to the pendulum
Correct answer: B. 7.9s
- A. 5.6s
- B. 7.9s
- C. 9.6s
- D. 9.8s
Explanation
Correct. According to time dilation in special relativity, the observed period increases for an observer moving at relativistic speedsIn summary, the correct option is **b. 7.9s** due to time dilation in the relativistic frame

About Simple Harmonic Motion
Simple harmonic motion is oscillation in which acceleration is directly proportional to displacement and directed toward the equilibrium position. Work includes displacement, velocity, acceleration, phase, period, frequency, amplitude and energy, with applications to springs and simple pendulums. The restoring force and the conditions for SHM distinguish it from general periodic motion.
