Starsat is a satellite orbiting with an altitude of 630 km. Tassat is another satellite orbiting with an altitude of 7 630 km. The radius of the Earth is 6370 km. The period of Tassat is 16452.6 seconds. The period of Starsat is
Compared to a low earth orbit satellite, which row of the table correctly describes the relative properties of a geostationary satellite of the same mass?
The Landsat 7 satellite orbits Earth at an altitude of approximately 700 km. The International Space station orbits at an altitude of 330km. Which of the following correctly compares the orbital velocity and orbital period of these satellites?
Which of the following best describes Newton’s analysis of escape velocity?
Wikipedia uses the following phrase: “the use of the relative movement and gravity of a planet or other celestial body to alter the path and speed of a spacecraft, typically in order to save propellant, time, and expense.” to describe:
A satellite of mass 1500 kg is orbiting a planet at an orbital radius of 2.6×107 m. It experiences a centripetal force of 4.7×103 N. The speed of the satellite is:
The table below contains data on the dwarf planet Eris. Using this data, calculate the acceleration due to gravity on the surface of Eris.
If r1 and T1 represent the distance and period of Planet 1 from a star of mass M and r2 and T2 represent the distance and period of Planet 2 from the same star, then the quantity (r1^3)/(T1^2 ) × (T2^2)/(r2^3 ) would equal:
The gravitational potential energy of a given mass is known at both Earth’s surface and at a fixed distance above Earth. What CANNOT be determined by comparing these two values of gravitational potential energy?
A 2000kg satellite in a circular orbit around the planet Saturn has a period of 380 hours. If the mass of Saturn is 5.7 x 1026 kg, what is the radius of the satellite’s orbit?
