Suppose you fell into an accretion disk that swept you into a supermassive black hole. on your way down, the disk radiates 10 % of your mass-energy, e=mc2. part a suppose that you weighed 120 pounds. what is your mass in kilograms? (recall that 1kg=2.2lb on earth.) part b calculate how much radiative energy will be produced by the accretion disk as a result of your fall into the black hole. part c calculate approximately how long a 100-watt light bulb would have to burn to radiate this same amount of energy
