Question

INSAT is an artificial satellite.
\[\left( {\text{A}} \right)\] True
\[\left( {\text{B}} \right)\] False

Answer 1

Hint:A satellite is a celestial body that revolves around a planet in a particular orbit. Earth is a planet and the moon revolves around the earth, therefore, the moon is the satellite of the earth. Mercury and Venus do not have satellites. All the remaining six planets have one or more satellites.

Complete step by step answer:
The satellite revolves around the planets due to the gravitational pull of the planets. The satellites have no light of their own. The satellite shines and becomes visible to us because they reflect the light of the sun falling on them.
Moon is a natural satellite of the earth. The moon revolves around the earth on a definite regular path. The gravitational attraction of the earth holds the moon in its orbit.
A man-made spacecraft placed in orbit around the earth is called an artificial satellite. An artificial satellite is located in orbit around the earth with the help of a launch vehicle called a rocket. The Rocket carries the artificial satellite from the earth to a height of a few hundred kilometers above it and gives it a sideways push.
The motion of an artificial satellite around the earth is because of the gravitational pull of the earth. In this way, the artificial satellite keeps on revolving around the earth continuously, without stopping. The first artificial satellite is Aryabhatta launched by India. It was launched in \[1975\]. Some other Indian satellites are Bharkara, INSAT, IRS, Rohini, Kalpana- \[1\]and EDUSAT.
INSAT stands for Indian National Satellite.
The agency responsible for the development of space science programmer’s in our country is the Indian space research organization (ISRO).
A communication satellite is a satellite that revolves around the earth in the earth’s equatorial plane in the same direction of rotation of the earth in \[24\] hours. The approximate height of the geostationary satellite from the surface of the earth is about \[{\text{36000 km}}\]. As it appears to be stationary concerning an observer on the earth, the communication satellite is also called the geostationary satellite.
Example: INSAT series satellite.
Therefore, INSAT is an artificial satellite that is a true statement.

Hence, the option A is correct.

Note: Uses of communication satellite:
-They are used for sending microwave and TV signals from one place to another.
-They are used for weather forecasting.
-They are used for detecting water resources locations and areas rich in ores.
-They are used for spying in enemy countries that is, it can be used for military purposes.
