What is the speed of a wave if it has a frequency of 5 Hz and a wavelength of 20 m?
Frequency(Î½) = 5 Hz = 5 s-1 Wavelength(Î») = 20 m Speed of wave = Î½ x Î» = 5 x 20 = 100 m/s ...
The period of sound wave that has frequency of 5 Hz is seconds?
The period is the reciprocal of the frequency, that is, in this case, 1/5 seconds. Note that such a sound is inaudible to human hears - a sound has to have at least 20 Hz or so to be heard. ...
What is the frequency of a wave with a velocity of 100 m s and a wavelength of 20 m?
Frequency = Velocity / Wavelength = 100 m/s / 20 m = 5 s-1 or 5 Hz.

With cell phone on vibrate what is the frequency of the vibration?
Probably something below 20 Hz. They are done with rotating motors with unbalanced shafts. Here is a page that shows lots of products. http://www.precisionmicrodrives.com/vibration_motors.php?_kk=cell%20phone%20vibrator%20motor&_kt=c8a02ca2-cd5f-4ac0-918f-9e11e3edc018&gclid=CNv2td_zuJ4CFQ8eDQodfUIwmA My guess is the shaft spins on the order of 5 or 20 rev/sec - giving a fundamental frequency of 5 to 20 Hz. Maybe 10 Hz... ...

How many times does 250 million go into 5 billion?
250 million is a quarter of 1 billion so there are 4 of them in 1 billion. So in 5 billion, there are 4*5 = 20 of them. Could hardly be simpler! 250 million is a quarter of 1 billion so there are 4 of them in 1 billion. So in 5 billion, there are 4*5 = 20 of them.
