could anyone explian how do we get energy from the nuclear fusion and fission thx isnt that fission requires bindling energy which use up energy

Dear forum contributer, The binding energy of a heavy nucleus is about 7 Mev per nucleon, whereas the binding energy of a medium-weight nucleus is about 8 Mev per nucleon. Therefore, the total kinetic energy liberated when a heavy nucleus undergoes symmetric fission is most nearly (A) 1876...

Why do we need much more energy for fusion than fission? PS: I apologize for my bad English,

OK, this is a question probably asked and answered before, but I've been wondering about this for years... Alkatran made a comment in the space-buoy thread about how mass changes with speed in SR. As you approach the speed of light, your mass increases towards infinity, and it would take...

"nuclear" fission produces quark mass A top quark is roughly 32 times more massive than a bottom quark. A charm quark is roughly 8 times more massive than a strange quark. And a down quark is roughly 2 times more massive than an up quark. In nuclear fission 2 neutrons yield 4 neutrons...

Hi, just unsure about a question I wonder if you can help me with: How do the neutrons released after nuclear fission differ from those absorbed to begin the reaction in the first place. I think this may be asking me about delayed neutrons, but this is more to do with how the neutrons are made...

hi guys, I am just wondering is it possible in reality to construct a fission reactor that will operate for decades or even centuries without refueling? Theoretically, we can do so if the macroscopic absorption cross section for the fertile nuclide equals that for the fissile species. and few...

another question. consider the possibility of designing a fission reactor that will operate for decades or even centuries without refueling. limit the investigation to thermal reactors with reaction rates = 2200 m/s cross section. Consider 3 fissile/fertile combinations: 1) Fissile= U-233...

Problem 19. At the point of fission, a nucleus of 235_U that has 92 protons is divded into two smaller spheres, each of which has 46 protons and a radius of 5.9*10^-15m. what is the magnitude of the repulsive force pushing these two spheres apart? Use 8.99*10^9 N*m^2/C^2. Note: How can you...

Could the center of the Earth's core be a critical mass of U-235 or other heavy metals, sustaining a fission reaction. (or might fusion be possible with the presures and magentic fields there? ). If not Earth what about Jupiter or larger exra solar planet? Merlin

Does Barium-144 have any useful purpose? All I really know about it is that it is a product of fission (one of the fission fragments from Uranium), which then decays into La-144, Ce-144, Pr-144, and Nd-144. Some radioisotopes are used in the medical field. What does Barium-144 bring to...
