Question

the orbital speed of a low orbit satellite is
a)zero
b)8ms-1
b)800ms-1
8000ms-1​

Answer 1

d) The orbital speed of low orbit satellite is equal to 8000 $ms^{-1}$.

What is a low orbit satellite?

• Low orbit satellites are satellites that orbit around the Earth between a height of 160 to 2000 kilometers above the Earth.
• These satellites are nearer to Earth than geosynchronous satellites and are used for communication, observation, supply, military reconnaissance, and other imaging purposes.

What is the orbital speed of a satellite?

• The orbital speed of a satellite is the minimum speed required by the satellite to move or orbit around the planet.
• The formula to determine the orbital speed is given by, $v_{orbit} =\sqrt\frac{GM}{R}$, where G is the gravitational constant, M is the mass of the planet around which the satellite orbits, and R is the radius of the orbit.
• The orbital speed of low earth orbit (LEO) satellites is known to be about 8000 $ms^{-1}$.

Therefore, the satellites revolving in lower orbits of earth called the low earth orbit satellites have an orbital speed of about 8000 $ms^{-1}$.

Answer 2

Answer:

option 'd' is the correct answer.

Explanation:

What is a low orbit satellite?

• Satellites in low orbit orbit around the Earth at a height of 160 to 2000 kilometres above the Earth's surface.
• These satellites are used for communication, observation, supply, military reconnaissance, and other imaging applications and are closer to Earth than geosynchronous satellites.

What is the orbit speed of a satellite?

• A satellite's orbital speed is the minimal speed required for it to move or orbit around the earth.
• The orbital speed is calculated using the formula, $v_{orbit}=\sqrt{\frac{GM}{R} },$where G is the gravitational constant, $M$ is the mass of the planet around which the satellite revolves, and $R$ is the orbital radius.
• Satellites in low earth orbit (LEO) have an orbital speed of about$8000 ms^{-1}.$

As a result, satellites in lower earth orbit, often known as low earth orbit satellites, have an orbital speed of roughly $8000 ms^{-1}.$
