Answer the questions - Assignment Example When a huge asteroid will slam on the surface of earth, it will have the equivalent of a thousand nuclear bombs exploding simultaneously killing everything. Then the class help made me understand that the catastrophe will not just end there but in fact will have some geological and weather changes. The explosion will create a plume that will be sent into the atmosphere creating an unbearable winter or ice age that no human being or any living things could survive. It is just geologically impossible to drill through the steel hard rock of the asteroid. In addition to that, it is also physically impossible to work through the conditions of a flying asteroid with very little gravity. The article and the video summarizes the basic principles of how a nuclear reactor works. Nuclear energy is produced through thermal fission in power plants called thermal reactors. The fission is produced when thermal neutrons â€Å"move in thermal equilibrium with the environment they are in" At a temperature of 550F which corresponds to a velocity of about 3700 meters per second†. These neutrons strike a uranium-235 nucleus causing the nucleus to split into 2 unequally sized nuclei called fission fragments that contributes to the heating in the fuel. In sum, uranium rods are inserted or dipped into the water either to make boil to create energy such as in the case of boiling water reactors or to pressurized the heated water such as in the case of pressurized water reactors. There are two common kinds of nuclear reactor that produces energy. First is the boiling water reactors and pressurized water reactors. Boiling water reactors produce energy by boiling water where the steam is used to turn the turbines which creates the energy to become electricity. Pressurized Water  Reactors (also known as PWRs) on the other hand works differently from boiling water reactors as it instead keep the water in pressure so
