black holes - 2025 PACE NSC

Question

"Extremal" examples of these objects, for which a equals one, violate a "third law" due to another quantity vanishing. The denominator of a formula for these objects' power contains the coefficient (0[1])15,360 (0[1])times pi. These objects motivated development of the holographic principle. (20[6]0[1])Jacob (20[4])Bekenstein helped to describe (20[1]0[1])the proportionality (20[1])between the (*) surface area of these objects (10[4]0[1])and entropy. (10[2]0[1])The (10[1])only knowable (10[2])information (10[1])about these (10[1])objects (10[2])is their mass, (10[3])charge, (10[1])and (10[1])angular (10[1])momentum, (10[7])according to the (10[1])no-hair theorem. (0[1])These objects may evaporate via Hawking radiation, which causes their Schwarzschild radius to decrease. (10[1])For 10 points, name these objects from which light cannot escape. ■END■ (10[2])
