If the Sun became a black hole, what would be its average density, assuming it to be a sphere with a radius equal to the Sun’s Schwarzschild radius? Compare your answer to the actual average density of the Sun.
Answer to relevant QuestionsIn Exercise 37, what would be the acceleration due to gravity at a distance of two Schwarzschild radii from the center of the “black hole” Sun? Compare your answer to the actual gravitational acceleration at a distance ...Let’s try a generalization of Exercise 41. Experimental evidence strongly indicates the existence of a huge black hole at the center of our galaxy (the Milky Way). This black hole is absorbing stars and increasing in mass ...An electron is accelerated to a speed of 1.50 x 108 m/.s At that speed, compare the relativistic results o the classical results for (a) The electron’s kinetic energy, (b) Its total energy, and (c) The magnitude of its ...Roughly speaking, the observable mass in our universe is all attributed to stars and gas clouds in the galaxies.
