The temperature at the center of a star is 1.30 to 10 ⁷ K and matter can then be ionized there.

At the center of this star, what is the product of the average square velocity of the electrons V _qm,e- with the average kinetic energy of the protons K _avg,P+ . In other words, find V _e- K _avg,P+ [in (nmJ)/s, n for nano 10 ^-9 ]. Use the mass of a proton: 1.66 10 ^-27 kg and that of an electron: 9.1 10 ^-31 kg.
