120 Hz means a vibration 120 cycles per second.
120kg is 120 Kilograms 120 Kilograms is 120,000 Grams.
120 yards = 109.728 meters.
A red blood cell typically lasts about 120 days.
120 grams = 4.23 ounces
1 yard = 3 ft., multiply 120 yds by 3 to find how many feet: 120 yds = 360 ft.
Time (seconds) = 1/Frequency (Hz) = 1/120 = 0.00834 seconds.
The vibration frequency of a phone is typically around 60 to 120 Hz, meaning it vibrates 60 to 120 times per second. This vibration frequency is what creates the buzzing sensation when your phone is set to vibrate mode.
Wavelength = speed/frequency = 120/6,000 = 2 centimeters
The velocity of a wave can be calculated by multiplying the wavelength with the frequency. In this case, the velocity would be 0.03 (wavelength) x 120 (frequency) = 3.6 m/s.
1/120 seconds!
Divide the speed by the frequency
In the Bahamas they use 120/240 and 120/208 voltage at 60 Hertz.
The voltage specification for a US electrical outlet is 120 volts, and the frequency specification is 60 Hz.
3.6 m/s
The three phase bridge rectifier has the highest ripple frequency. In a 60 Hz system, the ripple frequency would be 360 Hz. If it were a one phase bridge rectifier, the ripple frequency would be 120 Hz.
Main function of Variable Frequency Drive is to be able to run the AC Induction motors at different speeds (by changing the frequency). The speed is a function of frequency. N - Speed. F - Frequency P - Pole N= ( 120 x F)/ P
The formula you are looking for is f = N x P/120. (f) generator Frequency = (N) number of revolutions per minute of the engine x (P) number of magnetic poles / 120 2400 x 2 / 120 = 40 Hz
