You three were hit by the ejected electrons badly--at least you felt like you needed to think it was bad. It was time to fight back, and the energy you give had to be large enough to end this battle! That was when you saw a uranium-235 atom on the ground. Yes, this is it! You can let it go through fission 235 U 140 Ce +94 Zr +n so that you can use its disintegration energy. However, when you calculated the disintegration energy of this process, you found out that it is barely not enough to end the battle. Elecpatra was going through the same calculation and found the same flaw. She said "Let me turn into energy. When I touch my positron boyfriend, we both will turn into pure energy. Our love is quite intensive, you know. I am ready to do that to help you!" "But you will die!" You shouted, but Elecpatra just said "It was nice living with you," then went to fight the aliens. With the fission of a uranium-235 given above and an annihilation of an electron and a positron, how much energy can you get? Assume all particles are stationary. Masses of relevant particles: 235 U : 235.0439 140 Ce: 139.9054 u 94 Z. : 93.9063 u 1:1.00866 14 e : 5.485799 x 10-42 et : 5.485799 x 10-4 u 209 MeV 208 MeV 0.511 MeV 1.022 MeV
