Pendulum problems

  1. Jan 30, 2008 #1
    can someone explain how to find the period of a pendulum when given only the time?

    how do you find the period of a pendulum that makes 35 oscillations in 12 seconds? also the frequency?

    a simple pendulum can be used as an altimeter on a plane. how will the period of the pendulum cary as the plane moves from the runway to its cruising altitued of 1.00x10^4 meters?

    35 oscillations in 12 seconds


    Periodic time is the time taken for one oscillation

    Frequency is the number of oscillations per second
