A wave has a wave length of 18mm and a frequenc of 3hz at what speed does the wave travel?
The formula to calculate the speed of a wave is speed = wavelength x frequency. Plugging in the given values, speed = 18mm x 3Hz = 54 mm/s. The wave travels at a speed of 54 millimeters per second.
What is the period of a pendulum that takes 3 seconds to move forward and another 3 seconds to come back'?
The period of the pendulum is the time taken for one complete back-and-forth motion. In this case, since the pendulum takes 3 seconds to move away and 3 seconds to come back, the total time for one full cycle is 6 seconds. Therefore, the period of the pendulum is 6 seconds.
What are given in the problem?
f=3Hz T=0.33 sec. V=18m/s T=?

What is the radio frequency range?
freq range of rf is 3hz (extremely low frequency) to 300Ghz (extremely high frequency)
What is the branch address of sort code 40-16-08?

What effect on the brain wave pattern does hyperventilation have?
voluntary hyperventilation can cause a decrease in brain wave activity by reducing blood flow to the brain. It will typically cause a spike on an EEG recording of approximately 3Hz and has been studied with EEG tests when provoking seizures
What is the best frequency range for headphones?
As low as possible to as high as possible, but don't go just by frequency response. Anything by Sony or sennheiser are normally good. A good unknown brand I found were Urbanz. Decent frequency response is generally anything from 20Hz and lower to 25KHz and higher. For example, 10Hz to 28kHz is decent. Some professional headphones (such as professional sennheisers) boast 3Hz to 50kHz, but unless you are a music producer this is rarely necessary. Hope this has helped :)
A wave has a wavelength of 2mm and a frequency of 3Hz At what speed does the wave travel?
the formula for wave velocity/speed is: velocity= wavelength * wave frequencyvelocity is measured in meters/second (m/s), wavelength is measured in meters(m), and wave frequency is measured in hertz(hz).your wavelength is in millimeters, so convert it to meters and you get .002 meters.now, fill[replace] in the numbers you know for the variables in the formula.velocity(m/s)= .002(m) * 3(hz) do the multiplication and you get .006 the speed is .006 meters/second(m/s)you're welcome! :)

What is the frequency of X-ray waves?
There is a system of formal designation of the region of the electromagneticspectrum that we know how to generate and modulate for communication.The naming system differentiates among arbitrary sections of "radio" basedon slices of decades (10 times) of frequency and wavelength. You'll recognizesome of the abbreviations, like VHF and UHF:Very Low Frequency (VLF)3 - 30 KHz100,000 - 10,000 metersLow Frequency (LF)30 - 300 KHz10,000 - 1,000 metersMedium Frequency (MF)300 KHz - 3 MHz1,000 - 100 metersHigh Frequency (HF)3 - 30 MHz100 - 10 metersVery High Frequency (VHF)30 - 300 MHz10 - 1 meterUltra High Frequency (UHF)300 MHz - 3 GHz1 meter - 10 cmSuper High Frequency (SHF)3 - 30 GHz10 - 1 cmExtreme High Frequency (EHF)30 - 300 GHz1 cm - 1 mm
Why dont broadcast stations transmit at audio frequencies?
1) If information was transmitted at audio frequencies, then you would actually hear the signal. This would be identical to a speaker playing a song on your stereo. 2) Audio frequencies, in the world of radio frequencies, are long wave-length, low energy signals that can't travel long distances. Again, that's why you can only hear someone's stereo from within eyesight of the system. Human ears can detect from about 3Hz up to around 20KHz (some better than others). 3) True radio frequencies start at in the 100Khz range. This is your most basic radio that uses amplitude modulation (aka AM radio). Many people today that listen to the radio listen to frequency modulated (FM) stations. The difference between AM and FM is beyond the scope of the answer to this question. Being a higher frequency, the signals have more energy and can travel farther distances than audible frequencies. 4) Audible frequencies (sounds the human ear can pick up) can only "transmit" amplitude (loudness or volume) and frequency (high or low pitch). However, higher frequencies, such as those used for radio, can carry much more information than the volume and pitch of a signal. This is a direct result of radio frequencies being harmonics (integer multiples) of audible signals. For instance, if a radio signal has a frequency 20 times higher than the audio signal it is transmitting, then that radio signal can not only carry the audio signal, it can also carry other information, such as information about the broadcast station. A radio signal can "encode" information within the signal allowing more information to be carried than just the audio signal itself.
Basic difference between satellite and terrestrial communication system?
Satellite microwave transmission systems are similar to terrestrial microwave systems except that the signal travels from a ground station on Earth to a satellite and back to another ground station on Earth, thus achieving much greater distances than earthbound line-of-sight transmissions.Microwave communication requires line of sight and uses towers to transmit information, and hence have relatively smaller area coverage (generally 25-30 miles). One tower receives a signal, amplifies it, and sends it to the next tower. The microwave systems have the capability to carry large amount of data both digital and analog at high speed, and are mostly used for the transmission of telephone and television signals.Satellite communication covers a wider area due to its location, and is more useful for isolated locations (locations surrounded by oceans, mountains, or other geographic limitations)
