1.Explain how individual nuetrons are held together in a nucleus. given that like charges repel.
2.Why does the splitting of uranium-235 nuclei release energy, but the joining of hydrogen atoms also release energy?
3.Explain why a large spherical mass of uranium may be able to sustain a chain reaction while the same mass, spread into a flat sheet,could not.
4.Why is energy released in the process of fusing two small nuclei together?
5.How do control rods allow the fission chain reaction to be controlled?
6.How can a nuclear bomb contain sufficient fissionable material to explode,but be transported without exploding? (Use the term critical mass in your answer)
7.In the 1960s atmosheric testing of nuclear weapons was banned, but underground testing was allowed to continue. Why might this have been the case?

这些是物理题！
谁能解答出来啊！

2 （这题是问为什么铀235裂变放能，而H聚变也释放能量）小原子核聚变为大原子核也是有限度的,聚变只能发生到铁原子为止.
大原子核裂变为小原子核也是有限度的.只能发生到铁原子为止.
中等质量的原子核是比较稳定的.
从不稳定态到稳定态需要损失质量,释放能量
4 有质量亏损，E=mc^2
7 对别的国家进行核威慑，或者开发新能源
其他的题不太明白...
2.为什么不分裂的铀-235的原子核释放能量，但加入的氢原子，也释放能量？
3.解释，为何一个大球形大规模的铀可以维持链式反应，而同样的质量，蔓延到一个单位。
4.为什么所释放的能量在这个过程中融合两个小核一起合作？
5.如何让裂变链式反应加以控制
6.又如何能使核弹载有足够的可裂变材料爆炸，但没有运送爆炸？ （使用这个词临界质量，在您的答案）
7.在六十年代atmosheric核武器试验被禁止，但地下试验被允许继续下去。为什么会这样果真如此吗？
第一题翻译有点模糊 不好意思哦
我的英语不好，根据 aaa453365652 的翻译，第二问我可以回答：因为所有铀原子即使不裂变也会衰变，释放能量，它的这个性质是内在的，也就是原子内部的反应，跟傍边原子无关。（除非傍边原子有足够的能力使其内部性质发生变化）
1.用电荷相斥来解释原子核中的独立中子怎样相结合。
疯狂
