Assignment 1: Chapter 1
Problems: 2, 4, 8 c) and d) ONLY, 14 and word probem:
Write an equation for the radius of a black hole using dimensional analysis. The radius of a black hole can depend on:
1) the gravitational constant, G, which has units of L^3/ ( M T^2 )
2) the mass of the black hole
3) the speed of light
