A 4.28 m deep well acts as a closed pipe. When wind blows across the top, what is the third harmonic (f3) that it creates?

The third harmonic frequency from the wave speed is 60.1 Hz.

<h3>What is wavelength?</h3>

Wavelength is the distance between identical points in the adjacent cycles of a waveform signal propagated in space or along a wire.

Let's first find the wavelength of the wave.

The length wavelength relationship

\lambda = \frac{4}{3} L =  \frac{4}{3} . 4.28m = 5.706m

Now , we will find the third harmonic frequency from the wave speed formula:

v = f\lambda \\\\f = \frac{v}{\lambda} \\\\f = \frac{343\frac{m}{8} }{5.706m} \\\\f = 60.1 Hz

Therefore , the third harmonic (f3) is 60.1 Hz

Why is it important to include variety in your workouts
grigory [225]

Explanation:

Variety in to an exercise program allows the body to adapt to many demands, from high intensity exercise to slow, steady state exercise. Variety is important in a fitness program because it allows for your body to be challenged on a consistent basis and to overcome a plateau.

What is newton first law​
andrew11 [14]

Answer:

Newtons first law states that:

<em>If</em><em> </em><em>a</em><em> </em><em>body</em><em> </em><em>i</em><em>s</em><em> </em><em>in</em><em> </em><em>rest</em><em> </em><em>or</em><em> </em><em>motion</em><em> </em><em>in</em><em> </em><em>a</em><em> </em><em>straight</em><em> </em><em>line</em><em>,</em><em> </em><em>it</em><em> </em><em>remains</em><em> </em><em>at</em><em> </em><em>rest</em><em> </em><em>or</em><em> </em><em>at</em><em> </em><em>motion</em><em> </em><em>in</em><em> </em><em>a</em><em> </em><em>straight</em><em> </em><em>line</em><em> </em><em>with</em><em> </em><em>constant</em><em> </em><em>speed</em><em> </em><em>until</em><em> </em><em>and</em><em> </em><em>unless</em><em> </em><em>and</em><em> </em><em>external</em><em> </em><em>unbalanced</em><em> </em><em>force</em><em> </em><em>acts</em><em> </em><em>on</em><em> </em><em>it</em><em>.</em>

Explain why materials such as plastic foam, feathers, and fur are poor conductors of heat.
Firlakuza [10]
The atoms of some materials have no free electrons in their outer orbits. These electrons are busy doing other jobs, like being shared in the orbits of two adjacent atoms. They are so closely held that it is very difficult to pull them away. Most compounds of carbon and hydrogen are like this. 

<span>Plastics, whose molecules are made from long combinations of carbon and hydrogen atoms, have few or no free electrons. This means that plastics are poor conductors of electricity (and they are also poor conductors of heat). hope that helped.</span>

Explain why the amplitude of the wave did not change when you increased the frequency of the stimulation. how well did the resul
barxatty [35]
The amplitude did not change when the recurrence was expanded on the grounds that the long headstrong time of the heart forestalls adjustment. It is the most extreme removal or separation moved by a point on a vibrating body or wave measured from its balance position. It is equivalent to the one-a large portion of the length of the vibration way.
