Answer:
Step-by-step explanation:
Both dams and nuclear power plants involve energy transformations. Here are the energy transformations that occur in both:
1) Potential energy to kinetic energy: In both dams and nuclear power plants, potential energy is converted into kinetic energy. In a dam, water stored at a higher elevation possesses potential energy. When the water is released and flows down, its potential energy is converted into kinetic energy, which can be harnessed to turn turbines and generate electricity. Similarly, in a nuclear power plant, nuclear reactions release a tremendous amount of energy in the form of heat. This heat energy is used to produce steam, which in turn drives turbines to generate electricity.
2) Mechanical energy to electrical energy: In both dams and nuclear power plants, the kinetic energy is transformed into mechanical energy, which is then converted into electrical energy. In dams, the kinetic energy of flowing water turns the turbines, which are connected to generators that produce electricity. In nuclear power plants, the kinetic energy from the steam produced by the heat generated through nuclear reactions drives turbines connected to generators, ultimately producing electrical energy.
These are the main energy transformations that occur in both dams and nuclear power plants. They involve the conversion of potential energy to kinetic energy and the subsequent conversion of kinetic energy to electrical energy. These transformations play a crucial role in generating electricity from renewable sources (dams) and nuclear power.
