Answer:
Explanation:
The centripetal acceleration of a point moving by circular motion is given by:
where
is the angular velocity
r is the distance from the axis of rotation
The point on the wheel makes 5.0 revolutions per second, so the frequency is
and the angular velocity is
While the distance of the point from the axis of rotation is
Substituting, we find the acceleration:
The speed of the wave in the rod is
5044m/s
<h3>What is sound wave?</h3>
A sound wave is the pattern of disruption brought on by the movement of energy moving through a medium as it propagates away from the source of the sound (such as air, water, or any other liquid or solid substance). Pressure waves are produced when an item vibrates, such as a ringing phone, and these waves are known as sound waves. The surrounding medium's particles are disturbed by the pressure wave, and those particles disrupt the particles next to them, and so on. Like ocean waves, the disturbance's pattern causes outward movement in all directions. Usually in all directions and with decreased intensity as it gets further away from the source, the wave transmits the sound energy through the medium.
