What is the relation between the Hawking radiation and the observed radiation from x-ray binaries?
A. The observed radiation (e.g. in x-rays) is Hawking radiation. B. Hawking radiation probably dominates the observed radio emission. C. Hawking radiation probably dominates the observed gamma ray emission. D. Hawking radiation makes a negligible contribution at all wavelengths. Wed 2005 Apr 13: • Which of these gravity assists past the moon will slingshot the spacecraft furthest out in the solar system? Mon 2005 Apr 18: • As regards their Hawking radiation, more massive (as opposed to less massive) black holes are: A. Hotter and brighter. B. Hotter and fainter. C. Colder and brighter. D. Colder and fainter. E. Black holes are black, and they do not emit any kind of radiation. • A person on Earth watching you slingshot sees you apparently accelerate by 1000km/s in 1 second, equivalent to about 105 gees. This enormous acceleration kills you. A. True. B. False. Wed 2005 Apr 20: • Hubble’s law, v=H0d, states that the recession velocity v of a galaxy equals Hubble’s constant H0 times the d
