Please answer just questions 1 and 2.
10/27/17(F) /y's! 1) All the planets and other objects which orbit the Sun obey Kepler's law. Its third law says that T2 -2.97x10-19 r3, where T is the period of any object orbiting the Sun and r is its average distance from the Sun. If the period of an asteroid is 600 days, what is its average distance from the Sun? Note Msun 2.0x1030 kg. satellite whose mass is 50.0 kg is moving in a stable circular orbit 95 km above the surface of the Moon. Assume that the radius of the Earth is R(earth)-6.38x106 m, the mass M(Earth)-5.98x1024 kg, the mass M(Moon)-7.35x1022 kg and R(Moon)-1.74x106 m. G-6.67x10-11 Nm2/kg2 a. Compute the speed of the satellite 2) A b. Compute the period of the satellite c. Compute the force acting on the satellite at that height. 3) A 63.0 kg woman is on a spring scale in an elevator a What does it read (in N) if the elevator is at rest?Explanation / Answer
1) It is given that,
2.97e-19 r^3 = T^2
r^3 = (600*24*60*60)^2/2.97e-19 = 9.0484e33
r = (9.0484e33)^(1/3)
= 2.084*10^11 m answer
