In a longitudinal wave, amplitude can be measured
nignag [31]

Answer:

Compressions

Explanation:

A longitudinal wave is a wave in which the direction of propagation of the wave and the direction of the displacement of the particles of the wave are parallel.

As the wave propagates, the particles do not move, but, oscillate back and forth about their equilibrium position, and there are thus regions of high pressure called compressions and regions of low pressure called rarefactions.

The amplitude is thus the distance between successive compressions.

In 1656, the Burgmeister (mayor) of the town of Magdeburg, Germany, Otto Von Guericke, carried out a dramatic demonstration of t
Maksim231197 [3]

The force required to pull the two hemispheres apart is 4.2×10⁴ N and 29 number of horses are needed to pull these hemispheres apart.

<h3>What's the expression of force in terms of pressure?</h3>
  • Mathematically, force = pressure/area
  • Total area of the two hemispheres = 4π×(0.43)²= 2.3 m²
  • Total pressure on the hemispheres= 15 milibar (directed inward) + 940 milibar (atmospheric pressure) = 955 milibar

=955×100 N/m²= 9.55×10⁴ N/m²

  • Force on the hemispheres= 9.55×10⁴/2.3 = 4.2×10⁴ N

<h3>What's the minimum number of horses required to get 4.2×10⁴ N of force, if each horse can pull with a force of 1450N?</h3>

No. of horses required to separate the hemispheres = 4.2×10⁴/1450 = 29

Thus, we can conclude that the 29 horses are needed to pull the two hemispheres with a force of 4.2×10⁴ N.
