Here is how I would I explain it. Water is channeled through tunnels in the dam. The energy of water flowing through the dam’s tunnels cause turbines to turn. The turbines make generators move. Generators are machines that produce electricity. Engineers control the amount of water let through the dam. The process used to control this flow of water is called the intake system.

Hope this helps can’t do the diagram part.

Why are water vapor and aerosols important constituents of earth's atmosphere? choose all that apply.
RoseWind [281]

They are important because numerous serve as areas where water vapour can condense.

<h3></h3><h3>What is condensation?</h3>

The transformation of water vapour into liquid is known as condensation. The process is the opposite of evaporation, in which liquid water turns into a vapour. Either the air is chilled to its dew point or it gets too saturated with water vapour to retain any more water, causing condensation to occur.

Perform the following mathematical operation and report answer to the correct number of significant figures 143.6 divided by 21.
Svetllana [295]

The answer to the correct number of significant figures is 6.774.

<h3>What is quotient?</h3>

When a number(big) divided smaller number, the answer obtained greater than zero is called a quotient.

Divide 143.6 ÷ 21.2

143.6/21.2 = 1436/212

                  =6.77358

The quotient is rounded to three significant figures after decimal

143.6 ÷ 21.2 = 6.774

Thus, the answer to the correct number of significant figures is 6.774
