<h2>Answer:</h2>
The speed of the sound wave is 340 m/s. The correct option is C.
<h3>Explanation:</h3>
Here in question description the frequency and wave length is given and we have to find the velocity/speed of the sound wave.
Frequency is the time taken for the passage of one wave. Wavelength is the total length of crust and trough in meters.
The velocity is the product of frequency and wavelength.
V = λ ∙ f
By putting the values in given formula:
v = 100 Hz × 3.4 m = 340 m/s
Hence the speed of the wave is 340 m/s.
A natural gas power plant focuses on the use of non renewable energy resources.
<h3>What are non renewable energy?</h3>
Non-renewable energy are energy that comes from sources that cannot be exhausted.
- This energy can not be replaced because they don't get exhausted.
- Examples include energy form coal, natural gas, oil.
Therefore, natural gas power plant is an example of non renewable energy source.

Answer:
The angle formed of the rope with the surface = 40°
Force applied = 125Newtons
The displacement covered by the box =25metres
W= FDcos theta
[125×40×cos(40°) ] Joules
= [ (3125×0.76604444311)]Joules
= 2393.88888472 joules(ans)
