Answer:
1) Dam. Raises the water level of the river to create falling water. Also controls the flow of water. The reservoir that is formed is, in effect, stored energy.
2) Turbine. The force of falling water pushing against the turbine's blades causes the turbine to spin. A water turbine is much like a windmill, except the energy is provided by falling water instead of wind. The turbine converts the kinetic energy of falling water into mechanical energy.
3) Generator. Connected to the turbine by shafts and possibly gears so when the turbine spins it causes the generator to spin also. Converts the mechanical energy from the turbine into electric energy. Generators in hydropower plants work just like the generators in other types of power plants.
4) Transmission lines. Conduct electricity from the hydropower plant to homes and business.

Answer: The battles of Lexington and Concord were the first clashes of the United States War of independence, which occurred on April 19th, 1775 in Middlesex County, Massachusetts, in the towns of Lexington, Concord, Lincoln, Arlington and Cambridge. These events marked a point of no return in the war between the kingdom of great Britain and the thirteen colonies in the context of British North America. Around 700 regular British army soldiers, under the command of Lt. Col. Francis Smith, proceeded to capture and destroy some military positions that were supporting the militia in Concord. Dr. Joseph Warren alerted the colonies of this, who had planned that movement weeks before and had saved both people and material objects. They also learned the exact plans of the British attack the night before April 20th.
