Question

An object oscillates 260 times in 10 seconds. Calculate the time period and frequency. Will the sound produced be audible? Give reasons.​

Answer 1

Answer:

time period 26o/s

frequency=1/26hertz no sound is not produced audible

Answer 2

Answer:

Frequency = 26 Oscillation/sec

Time = 1/26 sec

Explanation:

260 Oscillation in 10 second

therefore 26 oscillations in 1 sec

Frequency = Oscillations per second

= 26 Oscillation/sec (Hz)

Time = 1/Frequency

= 1/26 sec

Normal Hearing Range of Human is

20 - 20,000 Hz

so the frequency produced by the object is audible.
