Since the Units presented are not in the International System we will proceed to convert them. We know that,
So the speed in SI would be
The change in frequency when the wave is reflected is
Or we can rearrange the equation as
f' = Apparent frequency
f = Original Frequency
c = Speed of light
Replacing,
Since the waves are reflected, hence the change in frequency at the gun is equal to twice the change in frequency
Therefore the increase in frequency is 2979.63Hz
Answer:
The wavelength is
The frequency is
Explanation:
From the question we are told that
The distance between two successive crest is 0.80 m
The velocity is v = 2.6 m/s
Generally wavelength is the distance between two successive crest
So
Now the frequency is mathematically represented as
Answer:
Newton's second law
Newton's second law, which states that the force F acting on a body is equal to the mass m of the body multiplied by the acceleration a of its centre of mass, F = ma, is the basic equation of motion in classical mechanics.
