- Check Your Understanding Galaxies are not single objects. How does the gravitiational force of one galaxy exerted on the “closer” stars of the other galaxy compare to those farther away? What effect would this have on the shape of the galaxies themselves?arrow_forwardThis is a proportional reasoning calculation. You will want to set up equations, but mostly to look at how the orbital distance affects the orbital velocity, or to set up a ratio. (Once you know how it changes you'll have to multiply by the value at the surface to get an answer in m/s.) At the surface of the exoplanet HD179079 b, the orbital velocity would be 1.72E+4 m/s. What would the orbital velocity be 8 radii above the surface? m/s.

- The radius Rh of a black hole is the radius of a mathematical sphere, called the event horizon, that is centered on the black hole. Information from events inside the event horizon cannot reach the outside world. According to Einstein's general theory of relativity, Rh = 2GM/c2, where M is the mass of the black hole and c is the speed of light. Suppose that you wish to study a black hole near it, at a radial distance of 48Rh. However, you do not want the difference in gravitational acceleration between your feet and your head to exceed 10 m/s2 when you are feet down (or head down) toward the black hole. (a) Take your height to be 1.5 m. What is the limit to the mass of the black hole you can tolerate at the given radial distance? Give the ratio of this mass to the mass MS of our Sun.
