  • PASSAGE-II: If the same motion occurs again and again, it is said to be repetitive motion. Repetitive motion that repeats itself at regular intervals of time is called periodic motion. A pendulum undergoes periodic motion. The time taken by a pendulum to complete its one oscillation is known as its time period. Frequency of a pendulum is defined as the number of oscillations completed in 1 second. If the time taken by the pendulum from C to A is 4 s, then the time taken by it to complete its one oscillation is

    A
    8 s
    B
    12 s
    C
    16 s
    D
    4 s

  • S-I : Quartz clocks are more accurate than pendulum clocks. S-II : Quartz clocks are periodic motion of simple pendulum for the measurement of time.

    A
    S-I and S-II are correct and S-II is the correct explanation of S-I.
    B
    S-I and S-II are correct but S-II is not the correct explanation of S-I.
    C
    S-I is correct but S-II is wrong.
    D
    S-I is wrong but S-II is correct.
