Answer
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(7,324 km)−−−−−−−√v=Gmp(7,324 km)−−−−−−−√
v=Gmp(15,522 km)−−−−−−−−√v=Gmp(15,522 km)−−−−−−−−√
v=Gmp(42,164 km)−−−−−−−−√v=Gmp(42,164 km)−−−−−−−−√
v=Gmp(48,115 km)−−−−−−−−√

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