Answer:
vibration = 500/s = 500Hz
therefore, frequency = 500Hz
time period = 1/frequency
= 1/500 = 0.002s/wave cycle
the sound is audible . our hearing range is 20Hz to 20000Hz. So as it's 500Hz , the sound is audible.
Hope it helped :)

Answer:
vibration, - 500/s- 500h2
therefore, frequency -- 500h2
time period - 1/frequency
- 1/500-- 0.0025/wave cycle.
