Answer to Question 1

As matter falls toward the central black hole, gravitational potential energy is converted into kinetic energy of motion. The conservation of angular momentum spins this material into an accretion disk in which kinetic energy is converted into thermal energy by the action friction as the gas flows. This heats the gas in the accretion disk to very high temperatures, and it radiates over a broad range of wavelengths in the electromagnetic spectrum. The ultimate conversion efficiency of gravitation potential energy into thermal energy can be quite high (10-40 of the rest energy of the matter, as compared to less than 1 for ordinary hydrogen fusion) so very large luminosities can be generated without requiring tremendous amounts of matter.

Answer to Question 2

TRUE

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
