Which two terms are related to the word "radius" in terms of discussing black holes?
light-year and solar mass
supermassive and stellar-mass
Schwarzschild and AU
dwarf and elliptical
The two terms related to the word "radius" in terms of discussing black holes are "Schwarzschild" and "AU."
The term Schwarzschild refers to the Schwarzschild radius, which is the radius that defines the event horizon of a non-rotating black hole. It is the distance from the singularity to the event horizon.
AU, on the other hand, stands for Astronomical Unit, which is a unit of measurement used in astronomy. It is the average distance between the Earth and the Sun and is often used as a reference for distances within our solar system. When discussing black holes, AU can be used to provide a sense of scale or size.
