Question

a pendulum perform 3600 oscillation in 1 hour. Explain that it is a seconds pendulum

Answer 1

If a pendulum oscillates 3600 times in a hour, then it is a seconds pendulum.

This is because we know that there are 60 minutes in a hour and 60 seconds in a hour. So, jointly there are 3600 seconds in a hour. So, if the pendulum oscillates 3600 times in a hour then it is a seconds pendulum.
