The international Space Station has an orbital period of 92.65 minutes an orbital speed of 7670 m/s, and a mass of about 4.19 x 10 kg. The mass of the Earth is 6 x 10 kg, and its radius is 6.37 x 10 m. At the Earth’s surface, the gravitational force on a 65 kg astronaut is 637 N. Assuming that its orbit is approximately circular, what is the radius of the ISS’ orbit? What is the gravitational force on this astronaut when she is inside the ISS?

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
