The Hubble Space Telescope moves in a circular orbit. Its distance above the Earth’s surface is 560 km and the radius of the Earth is 6400 km. It completes one orbit in 96 minutes.
Calculate its orbital speed in m/s to 3 significant figures.
(a)
A satellite is orbiting the Earth at an altitude of 35,786 km above the surface. The Earth has a radius of approximately 6400 km. If the satellite is moving at a speed of 3.07 km per second, calculate the time it would take for the satellite to orbit once around the Earth.
(a)
The Earth is approximately 150 million km from the Sun. Calculate the speed at which we are moving around the Sun. Give your answer in m/s to 3 sf.
(a)
Object X completes one orbit around its star every 35 days. It has an average radius of 1.5 x 1011 m from the star. Calculate the orbital speed of object X in m/s (give your answer to 3 s.f.)
(a)
KAPLANA-1 is an artificial satellite which orbits above the Earth. It has an orbital speed of 3.1 km/s and completes one orbit every day. If the diameter of the Earth is 12,800 km, calculate the height of the satellite above the Earth's surface. Give your answer in kilometres and round to 2 significant figures.
