Suppose you are at the center of a large freely-rotating horizontal turntable in a carnival funhouse. As you crawl toward the edge, the angular momentum of you and the turntable decreases increases remains the same, but the RPMs decreas decreases in direct proportion to your decrease in RPMs none of these

Stephan Hawkins worked extensively with theoretical gravitational physics. He is well known for his work with black holes. He passed on March 14th, 2018. It has been observed that a certain star (S2) in the Sagittarius A* (meaning in the direction of the constellation Sagittarius) is orbiting a supermassive black hole. If the period of S2 is 16year and the distance between the two is 1.79e13m. What is the mass of this black hole? (be careful with your units)

why to astronauts appear weightless while they are filmed performing activities inside the orbiting space shuttle they are high enough above the earths surface that they have escaped the pull of earths gravity the space shuttle has anti gravity devices on it that allow the astronauts to float inside it the astronauts are falling at the same rate as the space shuttle as it orbits around earth orbiting objects do not experience any gravity 62be3f03bafb0
