What else can I help you with?
What frequency would she hear as the siren moves away from her at the speed of Vs equals 49ms?
f = C fo / (C + vs)(Assuming speed of sound, c = 330 m/s),f = 330 fo / (330 +49 ) frequency that she would hear isf = 0.87 f0
FITT fo the FITT principle stands for full integrated training technique?
False. Stands for Frequency, Intensity, Time, and Type
Which uses single frequency digital signals?
I was told it is x(n) = 10*sin(2*pi*fo*Ts(n-1)) + 8*sin(2*pi*2*fo*Ts(n-1)) + 6*sin(2*pi*3*fo*Ts(n-1))
State the the frequency at antiresonance?
For a series a.c. circuit, resonance occurs when the inductive reactance is equal to the capacitive reactance. You can work out the frequency at which this occurs by inserting the variables into the following equation:XL = XC
Why fo scientists say the earth has to little AND to much ozone?
It is because ozone acts as a blanket to earth. It protects us from high frequency UV rays.
What is threshold frequency?
Threshold frequency is the minimum frequency of light required to eject electrons from a metal surface in the photoelectric effect. Below this frequency, no electrons are emitted regardless of intensity. It is a characteristic property of each metal and is used to determine the work function of the metal.
How does a tank circuit filter out frequencies?
Without writing a book, the tank circuit (tank) is what is called a tuned circuit. The basic tank circuit has an inductive component (a coil) and a capacitive component (a cap). There are a couple of concepts that you need to get a handle on. A tank has a given "resonance" based on the net inductance and capacitance. It has one frequency that it really likes to run at. That's the resonant frequency (fo). The tank is tuned for that fo. A signal at that frequency that is put into the stage that has a tank filter will cause the tank to "ring" electronically. The signal oscillates in the tank, and, because it's the fo for that tank, some maximum amplitude (gain) will be attained. The signal is then coupled out. Other signals of a slightly different frequency will cause the tank to ring, but not as much. As a signal is put into the stage that is a bit higher or lower than the fo, it causes less oscillation, and it emerges at a lower amplitude. Notice that this applies to signals that are a bit above or a bit lower than the fo. The farther from the fo that a given signal is, the less oscillation it produces in the tank, and the less gain it will be given in that stage. Again (and it's worth repeating), signals both above and below the fo a given distance produce the same oscillation in the tank. That means the tank responds to both sides of the spectrum above and below the fo. Lastly, the tank can be "sharply tuned" or not. In a sharply tuned tank, the signals that are farther from fo cause little tank action, and those right around fo really get a lot of gain. In something less sharpely tuned, there is still a good bit of gain for frequencies higher or lower than the fo. We spoke of the tuning of the tank for a particular fo. Now we have to tune the tank for what is called quality (Q). This speaks to how "tightly" the tank is tuned. And we have to make a trade. If we want a lot gain at fo and little else, high Q is the way to go. There will be a ton of gain at fo, and the gain for frequencies above and below will drop like a rock. In a less tightly tuned tank, there will be better gain for the frequencies around fo, but not as great a gain for the fo itself as there would be in a high Q tank. That's the trade. Narrow tuning yields greater gain for the fo and lower "bandpass" while broader tuning will pass "more frequencies" (have a higher band pass) but with lower gain at and right around the fo than a high Q tank.
What is the formula fo?
the formula is FOR not fo
What is the behavior of RC RL series circuit?
The series circuit described (if understood correctly) is a series tank circuit. It is a tuned circuit. The C and the L are capacitance and inductance, respectively, and they are said to be in series. What that translates into is that as an AC signal passes through them, they "ring" electronically (they oscillate) a certain amount depending on the frequency of the signal that is put in. Based on the C and the L, there will be one frequency that the circuit will like to run at, and this will be the resonant frequency (fo) of the series tank circuit. A maximum amount of oscillation can be expected at fo, and the tank is tuned for that frequency. But what if a signal is above or below fo? Signals above and below fo will not cause as much oscillation as the one right at fo. And the farther from fo they are, the less oscillation they will cause. If we graph the output (eo) of a stage (with frequency on the x-axis and gain on the y-axis) that has this kind of tuned circuit in it, we'll see a sharp peak at fo and a general falling off on either side. The farther from fo the input signal is, the less gain. This is true for signals both above and below fo. There is a slight difference in response as regards the slope of the flanks of that peak. The lower frequencies will fall off "forever" but the higher ones will fall of about the same as the lower ones to a point and then will not suffer much more attenuation. That's because at frequencies above fo, the circuit will have stronger capacitive characteristics, and the higher fequency signals will be coupled through. A graph of this circuit can be seen by using the link provided. There is also a link to the Wikipedia article on the RLC circuit from which this graph came. Lastly, the amount of R in the RLC circuit will determine the quality factor (Q) of the circuit. The quality determines how high and how wide the peak on our graph will be. Higher R means less quality. Lower R will result in higher Q. The higher Q circuit will have a higher and sharper peak. The lower Q circuit will have a lower but wider peak. The quality is a determinant in bandpass. Lower Q circuits will have higher (broader or wider) bandpass.
Would there be a Doppler effect if the source of a wave is stationary and the observer is the one in motion?
Yes. The observer frequency fo= f( v + vo)/(v -vs) where f is the signal frequency, v is the speed of wave and vo is the speed of the observer towards the signal and vs is the speed of the signal toward the observer.

Fo is a legitimit agency in concation with avp.
