Answer: The answer is in the figure attached.
Explanation:
The Work 
done by a Force 
refers to the release of potential energy from a body that is moved by the application of that force to overcome a resistance along a path.
It should be noted that it is a scalar magnitude, and its unit in the <u>International System of Units</u> is the Joule (J). Therefore, 1 Joule is the work done by a force of 1 Newton when moving an object, in the direction of the force, along 1 meter:
However, in the British Engineering and Gravitational Systems its unit is Foot-pound (ft-lb). Where 
Now, when the applied force 
is constant and the direction of the force and the direction of the movement (traveled distance) 
are parallel, the equation to calculate it is:
So, taking into account the explanation above, the attached table shows the Work done for each situation.
If the absolute pressure of a gas is 550.280 kPa, its gage pressure is

a. 101.325 kPa.
b. 448.955 kPa.
c. 651.605 kPa.
d. 277.280 kPa.</span>
The answer is B.

Answer:
by answering your question
Answer:
v = wavelength * frequency
frequency = 5200 m/s / .2 m = 26000 / sec
20,000 / sec is optimistic for the upper frequency of human hearing
So 26,000 is above the hearing range for human ears
