The answer would be d 900Hz, because it is 900 is not 200 does not go into 900 evenly. The pipe will resonate a frequencies that 200 will go into evenly.
A Deep male voice could start as low as 80Hz. A prepubescent child ranges from 150 to 400Hz
Hot Wire hot wire is a resistive device ir drop is the same regardless of frequency hot wire can measure power true power regardless of frequency or phase angle two wires for power current and voltage both to convert to a measured temperature integration speed depending on the mass of the wire(s) hot wire can be a bimetal spiral connected directly to the pointer on the scale Moving Iron: the moving iron has a spring connected to an iron bar in a coil dc or ac will cause the iron to be magnetized the amount of current will increase the deflection normal 50hz 60hz and dc differences are very small the iron will have induced eddy currents causing higher frequency to have less deflection 400hz on airplanes for lighter transformers... need a different calibration see "Wigginton voltage tester" simplest moving iron i know of one moving part, the iron well 2 if you count the little compass on top to tell dc polarity large solid core so different for 60Hz then dc by perhaps 10%
No, actually they hear less than humans. They can hear frequencies beetwen 400Hz and 2000Hz, as humans can hear a bigger interval, from 20Hz to 20000Hz
It's a generator that creates 400hz AC signals, instead of 50 or 60hz. 400hz is often used on ships, because the equipment (generators, transformers) can be made much smaller.
1600HZ 400HZ x 4
The Nyquist Therorem states that the lowest sampling rate has to be equil to or greather than 2 times the highest frequency. Therefore the sampling rate should be 400Hz or more.
it doesnt have to be kept constant but is convenient little synchronous motors in clocks transformer core materials depend on frequency airplanes use 400hz for less iron and weight in transformers higher frequencies conductors are hollow and silver plated or clad easier to synchronize generators if they are at the same frequency
twice the frequency that is rectified.
You can make your static inverter to maintain 400Hz by means of compare the generated frequency of your inverter with the reference buildin frequency generator which is called local oscillator or multivibrator which is fixed at 400 Hz. If your inverter generate frequency grater or less than 400Hz then the comparison between the reference frequency and the generate frequency will produce the error signal to reduce or increase the generated frequence and send it out. This is the principle operation of the Electrical Power Generation System. Post this answer by : tassana.e@thaiairways.com

If you multiply the wavelength (in meters) and the frequency (in Hertz), you will get the speed of the wave (in meters per second).
That depends on the circuit. For a pure resistive circuit (no inductance and capacitance), the frequency will have no effect on the current.
One could slow the generator shaft RPM down by a factor of 6.66 as these generator heads are usually mechanical and driven from a gas or diesel engine.
