Is a risk to change the screen refresh rate in laptop from 59 to 60 Hz?
I don't think it would hurt. I changed the refresh rate of my laptop's LCD from 59 to 60 a month ago and its been working fine since. As long as 60 Hz is already shown as an option in your control panel or whatever, it should be OK.
Is 560 Hz a stronger or weaker signal than 7.83 Hz?
560 Hz is a stronger signal than 7.83 Hz because it has a higher frequency, which means it oscillates more times per second. In terms of human perception, 560 Hz falls within the audible range while 7.83 Hz is in the extremely low-frequency range known as the Schumann Resonance.
If the frequency spectrum of a signal has a bandwidth of 500 Hz with the highest frequency at 600 Hz what should be the sampling rate?
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.
An airplane taking off has how many hertz?
more than 20,000 hz.
Can people hear more than 50 hertz?
Yes, humans can hear frequencies higher than 50 Hz. The average human range of hearing is from 20 Hz to 20,000 Hz, but some people, especially younger individuals, may be able to hear frequencies higher than this range.
What is larger 20 million Hz or 5 million Hz?
20 of anything is larger than 5 of the same thing.
Why 400 HZ for air crafts?
400 Hz is used in aircraft because it allows transformers to be much smaller than if the frequency was lower. A 50 Hz transformer would weight eight times as much. But 400 Hz is not useful for transmitting over distances of more than a few hundred metres because of power losses.
Is 10 Hz high or low pitch?
10 Hz is considered a very low pitch. The human hearing range typically starts around 20 Hz, so a sound at 10 Hz would be perceived as more of a vibration or rumble rather than a distinct pitch.
Do gas turbines get more efficient with increasing size?
Yes. Check published efficiencies from all the industrial gas turbine manufacurers to see for yourself. The 50 Hz versions are significantly more efficient than 60 Hz of the same design without exception. 50 Hz engines for Europe etc. are scaled 1.2X compared with 60 Hz for U.S. market.
What hertz should a guitar tuner be set to?
You want to tune a guitar's 'A' string to 440 hz.
Is the frequency of 262 Hz lower than a not of a freqency of 880 Hz?
The greater the number the higher the frequency. Zero frequency is called DC in electricity. Audio frequencies start at 20 Hz (Hertz= cycles per second) and go up to 20,000 Hz. Adults usually can't hear above 12,000 Hz so this is why the teenagers use a ring tone of 13,000 Hz while in school. The teachers can't hear it. Refer to kHz which is 1,000 Hz. There for 20 kHz is 20,000 Hz.
Introduction of ultrasonic?
we know that human ear can not hear sounds of frequency less than 20Hz or more than about 20,000 Hz . Sounds of frequency higher than 20,000 Hz , which are inaudible to human ear, can be produced and are utilized in many useful ways. Such sounds are called ultrasonics
