Why does vibrating simple pendulum not produce any sound?
The lowest frequencies we can hear are about 20 Hz - 20 vibrations per second. If (for example) the pendulum moves back and forth once per second, it will produce sound at that frequency, which we are unable to hear. Also, the sound will be of a fairly low intensity.
How do you find determine the period of the pendulum A pupil obtains the following values for 20 oscillations of a pendulum 12.6s 12.7s 12.5s 12.6s 12.7s Determine the period of pendulum?
First take the average of your times:(12.6 + 12.7 + 12.5 + 12.6 + 12.7) / 5 = 12.62This is your average time for 20 oscillations. The period is the time for one oscillation, and therefore the period is 12.62/20 = 0.631 seconds.A complete oscillation is when the pendulum swings from the start position to the opposite position on the swing and back again. Assuming this is what you counted twenty of, then your pendulum is 10 cm long.If you counted 20 swings to each side, then you really only counted 10 oscillations. This means that your period would be 1.262, and would suggest that your pendulum is 40cm long.
What is the period of a wave with a frequency of 20 Hz and a wavelength of 2.0 m?
The period of a wave is the time it takes for one complete cycle to pass a point. It is the reciprocal of the frequency. Therefore, a wave with a frequency of 20 Hz would have a period of 0.05 seconds (1/20 = 0.05). The wavelength of 2.0 m is unrelated to the period in this case.
What is the frequency of a wave with a period of 0.125?
Time period = 1 / frequency. Frequency = 1 / time period. f = 1 / 0.005 = 200 Hz
Why a viberating pendulum does not produce sound?
A vibrating pendulum does not produce sound because the air surrounding it is not being disturbed enough to create sound waves. Sound is produced when an object vibrates and creates pressure waves in the air, but a pendulum swinging back and forth does not generate enough force to create audible sound waves.

A wave has frequency of 50 Hz what is the period of the wave?
Period = reciprocal of frequency ( 1 / frequency ) = 1/50 = 0.02 second = 20 milliseconds

If a pendulum takes 32 seconds to complete 20 oscillations. Calculate the time period?
Time period per oscillation=32/ 20=1.6 sec per oscillation.
If the duty cycle of a rectangular waveform is 20 percent and the signal is a logic 0 for 40µsec what is the signal frequency?
If the logic 0 is the 20% then the period is 2ms and the frequency is 500 Hz. If the logic 0 is the 80% then the period is 50us and the frequency is 20kHz
If a wave has frequency of 20 Hz what is the period of the wave?
.05 seconds
What is the ride's period of an amusement park ride has a frequency of 0.05 Hz?
20 s
What is the period of a 50 kHz sine wave?
Period = 1/frequency = 1/50,000 = 0.00002 second = 20 microseconds
What is the frequency of a wave with a period of 0.125?
Time period = 1 / frequency. Frequency = 1 / time period. f = 1 / 0.005 = 200 Hz

What is the period of a wave with a wave speed of 5 and a wavelenth of 20?
The period is 4 [insert units here]. To get to this answer you use the equation v= λ*ƒ which basically means velocity is equal to lambda (wavelength) times frequency. Next you insert the speed where velocity is then you insert the wavelength and try to find the frequency. Once you get the frequency which should be 1/4 Hz then you use the proportion: period ~ 1/frequency and then you know that the period is 4.
