2. Flowing water contain ____form of energy.
3. In hydroelectricity,_____
form of energy converts to _____
form.
Answers
Answer:
Answer 1) Solar energy into Electrical energy.
Answer 2) Kinetic.
Answer 3) Mechanical into Electrical.
Explanation:
Answer 1) In a solar cell, solar energy from the Sun is converted into electrical energy. This electrical energy is used by the various electrical appliances.
Answer 2) Water, like many substances, contains two kinds of energy. The first kind of energy is called kinetic energy. This is energy that is used during the execution of processes, such as movement. Because of kinetic energy water can flow and waves can exist.
But water can also contain potential energy. This is energy that is stored in the water. Stored, but not used. This energy can become useful when water starts to flow. It will be transferred to kinetic energy and this will cause movement.
so it is clear that flowing water have kinetic energy .
Answer 3) In hydroelectric power plant following sequence of energy transformation take place,
Kinetic energy of water to potential energy of water to mechanical energy of turbine to electric energy through generator.
