1. The problem statement, all variables and given/known data A deuteron, , is the nucleus of a hydrogen isotope and consists of one proton and one neutron. The plasma of deuterons in a nuclear fusion reactor must be heated to about 3.01×108 . What is the rms speed of the deuterons? What would the temperature of the plasma be if the deuterons had an rms speed equal to 9.0×10−2 ? 2. Relevant equations Vrms = √(3KT/m) 1/2mv2 = 3/2KT mVrms2/(3K) = T 3. The attempt at a solution I went over this about 100 times before giving up. The answer I know is 5.9x1010K but even with that I can't get the answer. It is driving me sort of crazy so I figured I would ask if someone could help. The K I am using is 1.38x10-23J/K and the m is 3.34x10-27kg help!
