Answer in, with therefore statementsarrow_forwardDetailed explanation of each step so I could study for a test C6M.7 Astronomers currently believe that every galaxy has a supermassive black hole at its center and that a typical galaxy has collided with other galaxies several times since the beginning of the universe. Imagine that the central black holes of two colliding galaxies end up, after the collision, orbiting each other in the middle of a cloud of dust and stars. Assume that the black holes have the same mass M (which maybe millions or even billions of times that of the sun) and each is initially in a circular orbit of radius R around the pair’s center of mass (which is halfway between them), and the surrounding cloud has no net angular momentum, as shown in figure C6.14. Over time, frictional interactions with the cloud cause the black holes to slowly spiral in toward each other. If their orbits remain approximately circular as they slowly spiral in, then thespeed of each in its circular orbit will be │V│ = 1/2 (GM/r)^1/2,…arrow_forwardPlease help me answer part A and Barrow_forward
