Can long distance space commucating be possible in am as well as FM?

No. They dare not for fear of the deadly FM syndrome. This is a little known but fatal disease which aliens get when they us FM cause by the very poor DJs and music played.

Why do you not use frequency modulation in long range transmission?
Frequency modulation is not used for long distance transmission because it has the problem of limited band width.
Why AM is used for long distance communication?
AM has a frequency range of 531 kHz to 1602 kHz and on the other hand FM has a frequency range between 8705 MHz to 108 MHz. If we talk about the bandwidth of AM then it is 1071 KHz and bandwidth of FM is 20.5 MHz.According to the bandwidth FM should be used for long distance transmission but it is not used for long distance but AM is used fir long distance transmissions. the answer is here.Long distance transmissions are also decided by the Spectrum of the Signal in frequency domain by doing the Fouriertransform of the Signal.If we draw the Spectrum of AM waves the we find that their is a main loop in the central part of the spectrum with a high frequency and on the left and right side of this loop their are side loop which are very smaller then the main loop. In FM information can be recover from the main loop only not from the side loops. On the other hand in AM waves all the loops in spectrum is of same size and information can be recover from all the loops.That is why AM is used for long distance transmission.Thnx -Vipin Jasoria
How do you make a speed calculator in c plus plus?
To calculate speed you need to know the distance travelled and the time taken to travel that distance such that Speed = Distance / Time. The result of this calculation gives the average speed without taking into account any periods of acceleration or deceleration. We can implement this using just one function: long double speed (const long double distance, const long double duration) { return distance / time; } Note that we use the term "duration" rather than "time" purely to aid readability; "time" implies a specific moment in time rather than a duration. We use a long double to cater for the widest possible range of values. However, if we want to ensure the most efficient calculation over a wide variety of numeric types, we would use a function template instead: template<typename T> T speed (const T& distance, const T& duration) { return distance / duration; } The distance and duration variables will typically be taken from input: int main () { double distance, duration; std::cout << "Enter the distance and duration: " std::cin >> distance >> duration; std::cout << "Speed = " << speed (distance, duration) << '\n'; } Note that the actual units of measurement are not important to the function because speed is denoted by the given distance per given time unit. That is, if we travel 100 meters in 10 seconds, then the speed is 10 meters per second, whereas if we travel 100 miles in 10 minutes, then we are travelling at 10 miles per minute. Thus when distance is 100 and duration is 10, the speed is 10. It is up to the caller to convert these units to something more meaningful: int main () { double distance, duration; std::cout << "Enter the distance in kilometers: "; std::cin >> distance; std::cout << "Enter the duration in hours: "; std::cin >> duration; std::cout << "Speed = " << speed (distance, duration) << " kilometers per hour\n"; } Note that the examples do not perform any error-checking upon the input. In production code when entering numbers from input you will typically input strings instead. You will then test the strings are valid before typecasting the strings to a numeric format such as double.
What is the disadvantage and advantage of photo diode and transistor?
photo diode donot work for long distance photo diode act as a receiver
What type of physical activity is an aerobics class?
A type of activity that uses (mainly) your lungs and respiration, eg. long distance running, swimming.
Is it possible to get an ex boyfriend back if you to are long distance apart?
anything is possible, distance is just a test to see how long love can travel
How long does it take for earth to orbit the sun in km?
It is impossible to answer the question because the aswer to "how long does it take" would be given in terms of time, whereas a km is a measure of distance in 1-dimensional space. It is not possible to represent time in terms of distance.
How long could an average person breathe in space?
There is no atmosphere in space. No breathing is possible.

What are possible ways to stay in space for long periods for long time?
Get the oxygen tank!!!!!
Why do gravity assists help reduce the cost of long-distance space missions?
It reduces the total fuel needed, making possible the use of smaller lighter and less expensive booster rockets.
If phones did work in outer space would they be charged for long distance?
yes but it isn't that long distance because the satelite's for the phone companies are orbiting the earth

What two inventions made long distance sea exploration possible in the 1400s?
The compass and the astrolabe.
Is it possible to fart in outerspace?
Yes so long as the presure in your space suit isn't to high.
How long will a girl date a guy long distance?
It depends on the girl, where she is in her life and what she's looking for. If she's just casually dating then she'll stay in the long distance relationship for as long as possible but if she's looking for marriage then she won't stick around for long
