to transfer large blocks of energy over long distance, which equal to half of electromagnetic wave length. (at 50 Hz approximately is 3000 km.)
mega = 1,000,000 1MHz = 1,000,000 Hz.
The slip measures the percentage by which the actual speed is less than the synchronous speed. AC motors have a synchronous speed of 3000 rpm on a 50 Hz system, or 3600 rpm on 50 Hz. Some motors might have a synchronous speed half or a third of those speeds (or less), because the synchronous speed must be divided by the number of pole-pairs. For a 50 Hz motor running at 2850 rpm the slip is (3000-2850)/3000 or 5%. The slip speed is 2850 rpm.
If a bulb has 50 Hz frequency and it's supply is 60 Hz frequency, it will still glow, despite the allowance of 10 HZ frequency.
Hz = hertz ,which is a measure of frequency. It is equivalent to cycles per second. Your home power is 60 Hz if you live in USA.
Answer 1000 RPM or 16.667 HZ, 50 Hz * 60 = 3000 RPM 3000 / 3 = 1000 RPM, or 50 HZ / 20 (1/3 of 50 Hz) * 60 seconds. Or Hz * 20 ( converts to RPM) For 4 pole then, Hz * 30 = RPM For 8 pole, Hz * 15 = RPM
Most speech is found in the band of 300 to 3000 Hz

There is a bit of an argument on the exact baseband pass frequency for telephone audio, but generally it is in the range of 300 hz to 3000 hz.
Fast.
Approximitely 3000 kmm
it is 500 mph
3000 knots
3000 / 6 = 500 miles per hour.
