- Answer the question in full details, thank you very much, Answer on the correct significant figures: Suppose you are a space traveler, and you land on the surface of a strange new planet. As stated in yourStarfleet Manual, your first job is to measure the acceleration due to gravity, g, on this planet. You construct an"Atwood machine”, which consists of two masses connected to a pulley by a string of negligible mass, asshown in the figure. One of the masses is m1 = 54.1 kg and the other is m2 = 44.0 kg. The pulley is auniform disk of mass M = 108.0 kg and radius r = 67.0 cm; it is mounted on frictionless bearings. Whenreleased from rest, the heavier mass moves down 21.1 cm in 0.57 s, and there is no slippage of the string onthe pulley. What is the magnitude of the acceleration of the blocks, in m/s^2 What is the acceleration due to gravity gg on this planet? Give the answer in m/s^2Assume the scale height of Oxygen molecules in the Earth’s atmosphere is 7 km. If the density of such molecules is 1020 per cm3 at sea level, what is the density at the altitude of the Space Station? You will need to look up the latter, and perhaps change units.Question 8 Satellite A and B are both in stable orbit of the Earth, but Satellite B is twice as far from the Earth's centre. Compared to Satellite A, the orbital period of Satellite B is a) 2.83 times larger O b) 1.41x larger c) The same d) 0.70 times as large e) 0.35 times as large BAZAART
