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.
Both the effects (l<span>engthening of the transmitted signal's wavelength and decrease in its frequency) indicates that the object is moving away from the observer, and this phenomenon is called Doppler effect.
In fact, when the object is moving away from the observer, the relative distance between two consecutive crests of the wave emitted by the object increases to the observer eyes, since he's moving away. This means that the wavelength appears larger, and since the frequency is inversely proportional to the wavelength, the frequency appears smaller.</span>
Answer. Balanced
Explanation. Balanced forces provides an equal reaction to each action. For example, if you push on a wall, your hand isn’t going to go through. This is because the push is equal to the pull and the forces are balanced.
Hope this helped, let me know if it’s correct so others can use it :)
Good luck
Answer:
f=4Hz
Explanation:
frequency of a wave if it has a wavelength of 3.0 m and a wave speed of 12m/s
v=fλ → f=v/λ
f=12/3
f=4Hz
The statement "<span>The motion of a pendulum for which the maximum displacement from equilibrium does not change is an example of simple harmonic motion." is true.
