Question

Two identical pendulums have the same period when measured in the factory. While one pendulum swings on earth, the other is taken on a spaceship traveling at 95% the speed of light. Assume that both pendulums operate under the influence of the same net force and swing through the same angle. When observed from earth, how many oscillations does the pendulum on the spaceship undergo compared to the pendulum on earth in a given time interval? more oscillations fewer oscillations the same number of oscillations This question will be shown after you complete previous question(s).
Pendulums

Answer 1

Because of effect of time dilation, a clock moving

with respect to an observer appears to run more slowly

than a clock that is at rest in the observer's frame.

When observed from earth, the pendulum on the spaceship

takes longer to complete one oscillation.

Therefore, the clock associated with that pendulum

will run slower (gives fewer oscillations as seen from the earth)

than the clock associated with the pendulum on earth.

Ans => B fewer oscillations
