Time left 0:55:27 You discover a new moon orbiting a planet. The moon has an orbital period of 4.2 weeks, and the average distance between the moon and planet is 6.5 x 10 km. Compare the planet's mass to that of Jupiter, which is 1.9 x 1027 kg. The planet has _times the mass of Jupiter. (You may assume that the moon's mass is negligible compared to the planet.) Answer. 4 Your unknown planet should have a mass that's fairly close to Jupiter's (not less than 0.2, and not more than 100 times Jupiter's mass). If you find an answer that is wildly different, you should check your procedure.Time left 0: A team led by Prof. Pepper at Lehigh recently discovered the planet KELT-11b. It has a mass of 0.195 M, and a radius of 1.37 RJ. What is its density (in kg/m3)? You will also need to know that the mass of Jupiter is M, = 1.898 x 1027 kg, and the radius of Jupiter is RJ = 6.9911 x 10' m. A press release about KELT-11b is available here: https://www1.lehigh.eduews/%E2%80%98styrofoam%E2%80%99-planet-may-help-solve-mystery-of-giant-planets Answer: 19.02 CheckYou are an astronaut with a mass of 9.8 kg. What is your weight on the Moon? Useful references: Mass of Moon = 7.348 x 1022 kg Radius of Moon = 1.737 x 106 m G = 6.674 x 10-11 N m2/kg2Time left 0:56:4 Some astrologers claim that your destiny is determined by the influence of the planets that are above the horizon at the moment of your birth. Assume that Saturn is at its closest point to Earth, where its gravitational influence is strongest. Compare the gravitational influence of Saturn (mass = 5.68 x 1026 kg; distance = 1.3 x 1012 m) to that of the doctor in attendance (mass = 80 kg; distance = 1 m). How many times stronger is Saturn's gravity than the doctor's? Answer: Check
