Many satellites orbit Earth at maximum altitudes above Earth's surface of 1000 km or less. Geosynchronous...
A geosynchronous orbit is a high-Earth orbit that allows satellites to match Earth's rotation. There is a 500-kg satellite working on the geosynchronous orbit. If this satellite transfers to a new orbit with half the height of the geosynchronous orbit, find (a) the height of the new orbit, (b) percentage change of the radius of the satellite orbit.
What is the height H above the earth's surface at which all geosynchronous satellites (regardless of mass) must be placed in orbit? Note: A satellite that goes around the earth once every 24 hours is called a geosynchronous satellite. Mass of Earth: 6*1024 kg, radius of Earth = 6400 km. Note that the distance of the satellite from the Earth (r) in the formula is the distance from the center of the Earth. When you find the total distance r,...
A 600 kg satellite is in a circular orbit at an altitude of 475 km above the Earth's surface. Because of air friction, the satellite eventually falls to the Earth's surface, where it hits the ground with a speed of 2.50 km/s. How much energy was transformed into internal energy by means of air friction? 1.88e10
A satellite of mass 42.5 kg in geosynchronous orbit at an altitude of 3.58 ✕ 104 km above the Earth's surface remains above the same spot on the Earth. Assume its orbit is circular. Find the magnitude of the gravitational force exerted by the Earth on the satellite. Hint: The answer is not 417 N
Telecommunication satellites travel in geosynchronous orbits. these satellites move in sync with the Earth surface and always stay above the same point on the surface of the earth. all satellites in geosynchronous orbit must be located in the equatorial plane. Please, explain why it has to stay in the equatorial plane. Please EXPLAIN why it has to stay in the equatorial plane. DRAW a simple diagram showing forces acting on such a satellite. Hint: For any stable orbit the centripetal...
Two Earth satellites, A and B, each of mass m, are to be launched into circular orbits about Earth's center. Satellite A is to orbit at an altitude of 6860 km. Satellite B is to orbit at an altitude of 19000 km. The radius of Earth REis 6370 km. (a) What is the ratio of the potential energy of satellite B to that of satellite A, in orbit? (b) What is the ratio of the kinetic energy of satellite B...
For communications purposes, satellites are typically placed in a circular geosynchronous orbit. If the orbit is in the equatorial plane of the Earth, it is called geostationary. A satellite’s orbital speed in a geostationary orbit is set to match the angular velocity Ωe of the rotating Earth (with mass M), so that as seen from the Earth the satellite is stationary above a fixed point on the Equator. For a satellite of mass m in a geostationary circular orbit then...
Two Earth satellites, A and B, each of mass m, are to be launched into circular orbits about Earth's center. Satellite A is to orbit at an altitude of 7500 km. Satellite B is to orbit at an altitude of 24800 km. The radius of Earth REis 6370 km. (a) What is the ratio of the potential energy of satellite B to that of satellite A, in orbit? (b) What is the ratio of the kinetic energy of satellite B...
Two Earth satellites, A and B, each of mass m, are to be launched into circular orbits about Earth's center. Satellite A is to orbit at an altitude of 7760 km. Satellite B is to orbit at an altitude of 23600 km. The radius of Earth Rgis 6370 km. (a) What is the ratio of the potential energy of satellite B to that of satellite A, in orbit? (b) What is the ratio of the kinetic energy of satellite B...
a satellite in a geosynchronous orbit remains above the same point on Earth 2. A satellite in a geosynchronous orbit remains above the same point on Earth provided it orbits in the equatorial plane in the same direction as Earth's rotation. (a) Calculate the speed of a satellite in such an orbit. (b) Calculate the total energy of a satellite in such an orbit.
