answer 14 not 16.1cm, answer 15 not 8.123 m/s, answer 16 not 19.6 m/s^2.

Answer 14.

The oscillator is completing 43 vibrations in 20.4 s hence the frequency of the oscillator i.e. the number of oscillations completed in one second is given by

n = 43/20.4 = 2.1078 Hz

The frequency of the wave is the same as ...
