Understanding Geosynchronous and Geostationary Orbits

What does it mean for a satellite to be in a geosynchronous orbit?

• It orbits the Earth twice a day.

• It orbits the Earth in 12 hours.

• Its orbital period matches the Earth's rotational period.

• It remains stationary above the North Pole.

How long is the orbital period of a geosynchronous satellite?

• 12 hours

• 24 hours

• 48 hours

• 23 hours, 56 minutes, and 4 seconds

What is a unique feature of geostationary orbits?

• They are inclined to the equator.

• They remain above the same point on the Earth's equator.

• They orbit the Earth in 12 hours.

• They are used for polar satellites.

Where must a geostationary satellite be positioned?

• Above the North Pole

• Above the South Pole

• Above any point on Earth

• Above the equator

What is the formula used to calculate the radius for a geosynchronous orbit?

• R = 4π^2 / T^2

• R = G * M / T^2

• R = T^3 / G

• R = T^2 * G * M / 4π^2

What is the gravitational constant used in the calculation?

• 3.14

• 6.67 x 10^-11 N m^2/kg^2

• 1.62 m/s^2

• 9.81 m/s^2

What is the calculated radius from the Earth's center to a geosynchronous satellite?

• 35,786 km

• 42,164 km

• 10,000 km

• 50,000 km

How high above the Earth's surface must a geosynchronous satellite be?

• 10,000 km

• 35,786 km

• 50,000 km

• 42,164 km

What is the practical application of geostationary satellites?

• Weather forecasting

• Both A and B

• Communication

• None of the above

What is the equivalent height in miles for a geosynchronous orbit?

• 30,000 miles

• 15,000 miles

• 22,236 miles

• 10,000 miles
