If a manmade object revolves around the earth or any other planet in a fixed orbit it is called .......... satellite.
................ satellites are used in the study of forests, deserts, oceans, polar ice on earth's surface. These are also used in exploration and management of natural resources. They also collect information which guides us in case of natural calamities like flood and earthquake.
The initial velocity (during launching) of the Mangalyaan, must be greater than ............ of the earth.
................ satellites help in locating any place on earth's surface by fixing the location in terms of its precise latitude and longitude.
................ satellites use specific waves to establish communication between differem locations in the world.
Satellite revolving around the earth at a height of 400 km above the earth's surface has a time period of about
If the height of the orbit of a satellite from the earth surface is increased, the tangential velocity of the satellite will
If the satellite is revolving in a high earth orbit parallel to the equator, then its time for one revolution around the earth is same as that of rotation of earth. As a result, the satellite appears to be stationary with respect to the earth. Therefore, these satellites are called satellites.
In third and fourth stages of PSI.V types of gel used respectively are ............ and .............. .
Satellites revolving around the earth with the time period same as that of rotation of earth are called ............ satellites.
If the height of the satellite orbit above the earth's surface is between 2000 km and 35780 km, the orbits are called ................ earth orbits.
In first and second stages of PSL.V types of gel used respectively are ............... and ............... .
................ satellite series launched by India helps in locating any place on earth's surface by fixing the location in terms of its precise latitude and longitude.
In space non-essential objects revolving around the earth are termed as .................. in space.
