Answer :
Explanation :
The word kinematics means the study of motion. Kinematic variables gives the description of the motion of the body.
Displacement, Velocity, acceleration and time are associated with the motion of particle.
Wavenumber is defined as the frequency of wave, which is measured in cycles per unit distance.
Wave number is also defines as:
where, is wavelength
since,
So,
Where, is angular frequency and
is velocity of wave.
Hence, the relationship between the angular wavenumber k and and kinamatic variable V is
The Newton’s law Nikolas would use to come up with this idea is the <span>Third law that states:
</span><span>When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
</span>
So, in this case, let's name the first Body A which is the skateboard and the second body B which is <span>the compressed carbon dioxide in a fire extinguisher. Then, as shown in the figure below, according to the Third law:
