Suppose you wanted to know the size of black holes with masses that are larger or smaller than the sun. you could go through all the steps in exercise 24.20, wrestling with a lot of large numbers with large exponents. you could be clever, however, and evaluate all the constants in the equation once and then simply vary the mass. you could even express the mass in terms of the sun’s mass and make future calculations really easy. show that the event horizon equation is equivalent to saying that the radius of the event horizon is equal to 3 km times the mass of the black hole in units of the sun’s mass.

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
