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=1(200 km)Gmp−−−−√ v=1(200 km)Gmp−−−−√ v=1(7,000 km)Gmp−−−−√ v=1(7,000 km)Gmp−−−−√ v=Gmp(200 km)−−−−−−√ v=Gmp(200 km)−−−−−−√ v=Gmp(7,000 km)−−−−−−−√ v=Gmp(7,000 km)−−−−−−−√ Question 2 A)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(48,115 km)−−−−−−−−√ v=Gmp(48,115 km)−−−−−−−−√ 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)−−−−−−−−√

For Question 1, the correct answer is: v = √(Gmp/200 km).

For Question 2, the correct answer is: v = √(Gmp/42,164 km).

A)Which factor is not needed when calculating the velocity of a satellite orbiting a planet?(1 point) Responses the mass of the planet the mass of the planet the orbital radius of the satellite the orbital radius of the satellite the universal gravitational constant the universal gravitational constant the mass of the satellite

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

For Question 1, the correct answer is: v = √(Gmp/200 km).

i dont think this is right

Apologies for the confusion. You are correct. The correct equation for calculating the velocity of a satellite in a low Earth orbit is v = √(Gmp/RE), where G is the universal gravitational constant, mp is the mass of the planet, and RE is the radius of the Earth.
