What could be used as evidence for an intermediate-mass black hole? O a. Its extreme brightness could suggest a higher mass that lies in the intermediate range. O b. It could have an extremely large jet sweeping out areas of the galaxy. It could show a cycle of becoming brighter and dimmer Oc. repeatedly over the span of a year. O d. It could have an extremely bright pulsar near it. What quantities should you measure, if you want to find the mass of a black hole in an x-ray binary system? O a The size of the companion star. O b. The orbital speed of the black hole around the centre of mass. Oc. The size of the accretion disk. Od. The orbital distance, period, and mass of the companion star. O e. The radius of the event horizon. Two people are in the same inertial reference frame only if O a. they are located at the same place, and both are at rest. O b. they are not moving with respect to each other. O c. they are located at the same place. O d. they are both in free fall. How does an isolated black hole change when it emits Hawking radiation over a long period of time? O The black hole loses mass and it emits radiation that becomes brighter and longer wavelength over time. O The black hole loses mass and it emits radiation that becomes brighter and shorter wavelength over time. O The black hole loses mass and it emits radiation that becomes dimmer and longer wavelength over time. O The black hole loses mass and it emits radiation that becomes dimmer and shorter wavelength over time.
