How is the energy that powers radio galaxies,quasars,and other active galactic nuclei produced?
A)by nuclear fusion near a central black hole
B)by magnetic fields that trap and accelerate charged particles,which then radiate high amounts of energy
C)by matter that has been converted to pure energy being shot out as jets by a central black hole
D)by gravity,which converts potential energy of matter falling toward a central black hole into kinetic energy,which is then converted to thermal energy by collisions among the particles of matter
E)by matter-antimatter annihilation near a central black hole

Question

Quizplus · Accepted Answer

The energy that powers radio galaxies, quasars, and other active galactic nuclei is primarily produced by the gravitational force of a central supermassive black hole. As matter falls towards the black hole, its potential energy is converted into kinetic energy, which then becomes thermal energy due to collisions among particles. This process generates the immense amounts of energy observed in these astronomical phenomena.
