Nuclear fusion is the process by which stars, including the Sun, generate their energy. In a fusion reaction, atomic nuclei ‘fuse’ together to form heavier nuclei. For this to happen, the nuclei need to have enough energy to overcome therepulsiveforce they experience because they are both p...
Where does Nuclear Fusion happen?A. Nebula.B. Outside of very large clouds.C. Outside of gas.D. Inside and outside of very large clouds and gas.4. What does the underlined word “gas" mean in this passage?A.天然气B.汽油C.毒气D.气体5.determines the color of the star.A. The ...
The 12C + 12C fusion reaction is one of the most important reactions in the stellar evolution. Due to its complicated reaction mechanism, there is great uncertainty in the reaction rate which limits our understanding of various stellar objects, such as explosions on the surface of neutron stars,...
How does nuclear fusion begin? A) What are the products in the fission of uranium-235 that make possible a nuclear chain reaction? B) What is the purpose of placing control rods among uranium samples in a nuclear reactor? Summarize how an atomic bomb works, including how the nuclear explosi...
All these events happen in about 600 billionths of a second (550 billionths of a second for the fission bomb implosion, 50 billionths of a second for the fusion events). The result is an immense explosion with a 10,000-kiloton yield — 700 times more powerful than the Little Boy explo...
No, probably. Here's why:Nuclear power plants will be unlikely to go into a meltdown scenarioin the event of operators' absence. After several days, most will shut themselves down if they have not received maintenance. What would happen if you touched a nuclear fuel rod?
Nuclear fission can happen spontaneously, in which we case we call it radioactive decay (the conversion of unstable, radioactive isotopes into stable atoms that aren't radioactive). It can also be made to happen on demand—which is how we get energy out of atoms in nuclear power plants. ...
Where does nuclear fusion occur in the Sun? How does radiometric dating use fission? What is spontaneous fission? Where in the sun do fusion reactions happen? What is fusion in states of matter? During nuclear fusion in the sun, do two hydrogen atoms fuse together to form a helium atom, ...
Fusion does produce some radioactivity in the materials comprising the reactor. But this isn't expected to be anywhere near as long-lived or intense as theradioactive waste produced by nuclear fission—making it potentially a safer and more palatable choice than conventional nuclear power. ...
