It takes the planet Jupiter 12 years to orbit the Sun once. What is the average distance from Jupiter to the Sun? (The distance from the Earth to the Sun is 1.5 x 1011 m.)
9.7 x 1011 m.
3.9 x1011 m.
5.2 x 1011 m.
7.9 x 1011 m.
An Earth satellite of mass m revolves at a height from the surface of the Earth. If R is the Earth's radius and g is the acceleration due to gravity at the surface of the Earth, then the velocity of the satellite is given by:
gR / R+h.
√ (gR / R+h).
2gR²/ R+hD.
√ [gR²/ (R+h)].
