Question

Let G be the universal gravitational constant and mp be the mass of the planet a satellite is orbiting. Which equation could be used to find the velocity of the satellite if it is placed in a low Earth orbit?(1 point)
Responses

v=Gmp(200 km)−−−−−−√
v=Gmp(200 km)−−−−−−√

v=1(7,000 km)Gmp−−−−√
v=1(7,000 km)Gmp−−−−√

v=Gmp(7,000 km)−−−−−−−√
v=Gmp(7,000 km)−−−−−−−√

v=1(200 km)Gmp−−−−√

Answer 1

The correct equation to find the velocity of the satellite if it is placed in a low Earth orbit is:

v = √(Gmp / (200 km))

Answer 2

Which factor is not needed when calculating the velocity of a satellite orbiting a planet?(1 point)
Responses

the mass of the satellite
the mass of the satellite

the orbital radius of the satellite
the orbital radius of the satellite

the universal gravitational constant
the universal gravitational constant

the mass of the planet

Answer 3

The factor that is not needed when calculating the velocity of a satellite orbiting a planet is:

the mass of the satellite.

Answer 4

Let G be the universal gravitational constant and mp be the mass of the planet a satellite is orbiting. Which equation could be used to find the velocity of the satellite if it is placed in a geostationary orbit?(1 point)
Responses

v=Gmp(15,522 km)−−−−−−−−√
v=Gmp(15,522 km)−−−−−−−−√

v=Gmp(7,324 km)−−−−−−−√
v=Gmp(7,324 km)−−−−−−−√

v=Gmp(42,164 km)−−−−−−−−√
v=Gmp(42,164 km)−−−−−−−−√

v=Gmp(48,115 km)−−−−−−−−√

Answer 5

The correct equation to find the velocity of the satellite if it is placed in a geostationary orbit is:

v = √(Gmp / (42,164 km))
