Identify the correct definition:

 1 If after every certain interval of time, a particle repeats its motion, then the motion is called periodic motion. 2 To and fro motion of a particle is called oscillatory motion. 3 Oscillatory motion described in terms of single sine and cosine functions is called simple harmonic motion. 4 All of the above

A simple pendulum attached to the ceiling of a stationary lift has a time period of 1 s. The distance y covered by the lift moving downward varies with time as y = 3.75 ${\mathrm{t}}^{2}$, where y is in meters and t is in seconds. If g = 10 $\mathrm{m}/{\mathrm{s}}^{2}$, then the time period of the pendulum will be:

 1 4 s 2 6 s 3 2 s 4 12 s
