The tensile stress in a thick copper bar is 99.5 % of its elastic breaking point of 13.0× 10¹⁰ N/m² . If a 500-Hz sound wave is
dimaraw [331]

The speed of the wave in the rod is

The speed of the wave in the rod is $v = \sqrt{\frac{Y}{\rho}} = \sqrt{\frac{20\times 10^{10}\ \mathrm{N/m^2}}{7.86\times 10^3\ \mathrm{kg/m^3}}} = 5044\ \mathrm{m/s}$

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.

Medulla Oblongata is lowest part of brain stem which is most vital part of the brain.

Thalamus is a small region of the brain located above the brain stem. Its main function is to transmit sensory signals to cerebral cortex.

Brain stem act as relay center connecting the cerebrum and cerebellum to the spinal chord.

Hypothalamus is the mid brain located near the pituitary glands. It is very small region of the brain but it plays an important role in maintaining the body temperature and releasing the hormones.
