Answer:
a. 0.18Hz
b. 0.56m/s
Explanation:
From the question we can deduct the following parameters
The wavelength, λ is define as the distance between two successful crest or trough and from the question we conclude that wavelength is 3.17m.
Also the period of the wave T can be computed as
T=22.6/4
T=5.65secs.
a. To compute the frequency, recall that frequency, F=1/period.
Hence,
F=1/5.65
F=0.18Hz
b. Next we compute the wave speed.
Wave speed=frequency *wavelength
Wave speed =0.18*3.17
Wave speed =0.56m/s
Answer:
1. The lowest stratum of the atmosphere
troposphere
2. Most of the earth's ozone is located in the
stratosphere
3. Earth coldest temperature occur in the
mesosphere
Explanation:
Flow chart of a system is a diagrammatic representation of how that system performs it's functions.
<h3>The flow chart of internal combustion engine</h3>
The flow chart of internal combustion engine is the diagrammatic representation of how the engine works.
The inlet valve of the engine is the valve that allows for the entry of fuel-air mixture into the engine.
The exhaust valve of the engine is the allows for the outflow of used gases from the engine.
From the attached flow chart, Intake valves are opened to allow the flow of an air/fuel mixture into the engine's cylinders prior to compression and ignition, while exhaust valves open to permit the expulsion of exhaust gases from the combustion process after ignition has occurred.

Answer:
Part a)
Rate of charge flow is known as electric current
Part b)
Average current flow is
Part c)
As we know that current density is current per unit area
Explanation:
As we know that angular frequency of rotation is
now by basic definition of electric current
Part a)
Rate of charge flow is known as electric current
so here we have
Part b)
here we know that
now we have
Part c)
As we know that current density is current per unit area
So we have
Answer:
Distance: -30.0 cm; image is virtual, upright, enlarged
Explanation:
We can find the distance of the image using the lens equation:
where:
f = 15.0 cm is the focal length of the lens (positive for a converging lens)
p = 10.0 cm is the distance of the object from the lens
q is the distance of the image from the lens
Solving for q,
The negative sign tells us that the image is virtual (on the same side of the object, and it cannot be projected on a screen).
The magnification can be found as
The magnification gives us the ratio of the size of the image to that of the object: since here |M| = 3, this means that the image is 3 times larger than the object.
Also, the fact that the magnification is positive tells us that the image is upright.
