- Please answer the question and subquestions entirely. This is one single question. According to the official guideline, I can ask two subquestions! Thank you! 1) Two point masses are placed 10.0 cm apart and attract each other with a force of 10.0 N. Find the force of gravitational attraction between the masses when they are placed 5.00 cm apart. 3.00 N 4.50 N 20.0 N 40.0 N a) The radius of the orbit of a certain asteroid is four astronomical units. What is the period (in years) of this asteroid? 2 years 4 years 6 years 8 years b) A satellite is orbiting the earth at an altitude where the acceleration due to gravity is 8.70 m/s 2. What is its speed? 2.65 x 103 m/s 7.45 x 103 m/s 7.68 x 103 m/s 7.91 x 103 m/sAn earth-like planet with a mass of 6.00×1024 kg has a space station of mass 4.60×104 kg orbiting it at a distance of 5.00×105 km. What is the gravitational potential energy between the space station and the planet? (We can simplify the Gravitational Constant G to 6.7x10-11 Nm2/kg) (calculate in J)How do you determine the mass of a planet with just its distance to another object, and the gravitational field intensity?
- Why don't you feel a gravitational force from the text book you're reading?What is the approximate escape speed in m/s from a tiny moon in orbit about Mars that has a mass of 0.97 x 1016 kg and a radius of 10.0 km. The gravitational constant is 6.67 x 10-11m3kg-1s-2Black Hole Gravity III. If a person is falling feet first into a black hole, her feet are at the Schwarzschild radius, and her head is outside the radius by an additional 2 m, what is the approximate ratio of the gravitational acceleration felt at her feet compared to the gravitational acceleration felt at her head? Would she be stretched and squished differently at her head and feet? Assume the gravitational acceleration is g = GM⁄r2.
