Central black holes can be very efficient for converting the mass-energy of infalling matter to thermal energy in the accretion disk.Roughly what percentage of the mass-energy can be converted to other forms of energy as matter falls into a black hole?
A)0.7%
B)1% - 4%
C)10 - 40%
D)100%

According to current models, 10-40% of the mass-energy can be converted to other forms of energy as matter falls into a black hole. This is due to the intense gravitational forces and frictional heating in the accretion disk. The efficiency of conversion can vary depending on the properties of the black hole and the type of matter falling into it.
