About 35 electron volts of energy is required to ionize an air molecule. A 2 MeV radioactive particle passing through the air would therefore be expected to result in the ionizing of approximately ___ air molecules.

The slope of a velocity time graph over any interval of time gives the during that interval

5. why should the electrons be placed separate from each other (why not together)?
