Dec 03, 2016 · Calculate the speed of a satellite moving in a stable circular orbit about the Earth at a height of 5000 km. v = 1 answer 1) Determine the angular momentum of the Neptune about its rotation axis (assume the Neptune is a uniform sphere). Height, h = 20 200 × 1000 m In a stable orbit, linear speed of satellite is = 2.02 × 107 m Ί๶๵GM Radius of orbit, r = (6.37 × 106) + (2.02 × 107) = 2.657 × 107 m v = r . This linear speed is high enough for the satellite to move in a circular orbit around Linear speed the Earth. Centripetal acceleration is the same as gravitational ...One astronomical unit (A.U.) is the semi-major axis of Earth's orbit around the Sun — essentially the average distance between Earth and the Sun. Using these units for time and distance, we can write Kepler's third law for any planet as where T is the planet's sidereal orbital period, and r is the length of its semi-major axis (average distance).We analytically work out the long-term orbital perturbations induced by a homogeneous circular ring of radius R r and mass m r on the motion of a test particle in the cases (I): r > R r and (II): r < R r. In order to extend the validity of our analysis to the orbital configurations of, e.g., some proposed spacecraft-based mission for fundamental physics like LISA and ASTROD, of possible annuli ... dcyf lies rico crimesaimbot roblox scriptoyeku ofun olodumare
