Question

Sun solar energy dam complete the analogy​

Answer 1

Explanation:

Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun’s core and fuse to create a helium atom.

This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy. In its core, the sun fuses about 620 million metric tons of hydrogen every second. The PP chain reaction occurs in other stars that are about the size of our sun, and provides them with continuous energy and heat. The temperature for these stars is around 4 million degrees on the Kelvin scale (about 4 million degrees Celsius, 7 million degrees Fahrenheit).

In stars that are about 1.3 times bigger than the sun, the CNO cycle drives the creation of energy. The CNO cycle also converts hydrogen to helium, but relies on carbon, nitrogen, and oxygen (C, N, and O) to do so. Currently, less than 2% of the sun’s energy is created by the CNO cycle.

Nuclear fusion by the PP chain reaction or CNO cycle releases tremendous amounts of energy in the form of waves and particles. Solar energy is constantly flowing away from the sun and throughout the solar system. Solar energy warms the Earth, causes wind and weather, and sustains plant and animal life.

Answer 2

The correct analogy for dams is hydroelectric energy/power.

• Hydroelectric power is a renewable energy source that generates electricity by harnessing the power of moving water.
• Dams are commonly used in large-scale hydropower projects.
• The potential energy stored in a water reservoir behind a dam is converted to mechanical energy, also known as kinetic energy, by a hydroelectric dam.
• The kinetic energy of the water flowing down the dam is used to drive a turbine.
• The turbine's mechanical energy is converted into electricity by the generator.
• Dams are commonly used to construct a reservoir in which water is kept at a specific height.
• The amount of energy generated is determined by the height of the reservoir and the velocity at which water flows through the turbines.
• The hydroelectric power equation can be used to calculate this.
• Dams are built for a variety of reasons, including the generation of hydroelectric power and the control of river flow and flooding.
• Small-sized dams called weirs are erected in some rivers to manage and measure water flow.
