Can an artificial satellite be put into orbit in such a way?
Not possible, because a satellite will appear stationary only when it revolves in an orbit concentric and coplanar with the equatorial plane having time period of revolution 24 hours and it should have the sense of revolution from west to east that of earth.As New Delhi is not in the equatorial plane, hence it will not …
Why does a satellite not need any fuel to circle around the earth is it possible to put an artificial satellite in an orbit such that it always remains visible over Lucknow?
Answer. It does not need fuel because it runs on solar energy. Yes, it is possible. Geostationary satellites remain fixed at one point as their speed of revolution is same as the speed of rotation of the earth.
Is it possible to put an artificial satellite in an orbit such that it always remains visible over Lucknow?
Answer: It is possible to place an artificial satellite in an orbit, such that it is always visible over New Delhi. Explanation: A satellite remains always visible only if it revolves in the equatorial plane with a period of revolution equal to that of the earth.
Is it possible to put an artificial satellite into an orbit in such a way that it will always remain directly over New Delhi justify?
it possible to put an artifical1 satellite into orbit in such a way that it will always remain directly over New Delhi. As New Delhi is not in the equatorial plane, hence it will not be possible to put a geostationary satellite over New Delhi.
Which of the following is false for a satellite in an orbit?
A satellite in an orbit is a freely falling body. It does not require any energy for its motion in the orbit and its speed is constant.
Which of the following is the most fundamental for satellite navigation?
Which of the following is the most fundamental for satellite navigation? Explanation: All of the satellite navigation equations have either satellite position or velocity as a variable.
Why FM is used in satellite communication?
The main advantage of using SCPC FM modulation with syllabic Companding in satellite communication is to increase the limited capacity and this capacity increment is fully depends on the syllabic companding.
How is FM better than AM?
Each FM station is allocated 150 kHz of bandwidth, which is 15 times that of an AM station. This means that an FM station can transmit 15 times as much information as an AM station and explains why music sounds so much better on FM.
Why is FM used for audio transmission?
Frequency modulation (FM) Because the frequency of a radio wave is less vulnerable to noise than the amplitude, FM was originally introduced to reduce noise and improve the quality of radio reception. FM, though, because of its relative noise-free reception, is used to transmit the audio part of the television signal.
Does TV use AM or FM?
Television broadcasts also use radio waves (see Figure above). For TV broadcasts, sounds are encoded with frequency modulation, and pictures are encoded with amplitude modulation. The encoded waves are broadcast from a TV tower.
Can FM be used for picture transmission?
The sound program accompanying a television picture signal is transmitted by equipment similar to that used for frequency-modulated (FM) radio broadcasting.
How far do FM transmitters work?
What is the maximum distance an FM transmitter can broadcast without a license? The quick answer is approximately 200 feet for an FM Transmitter covered under Part 15 (Read FCC Public Notice dated July 24, 1991). The full answer is much more complicated than that: 250 µV/meter @ 3 meters (also measured as 48 dBuV/m).
