Answer:
All we need to know for this is SUVAT equations. There are 5 SUVAT equations you need to learn. S = distance, U = initial velocity, V = final velocity, A = acceleration, T = time V= U + AT V^2 = U^2 + 2AS S = UT + 1/2AT^2 S = VT -

Answer:
Explanation:
Given:
- original frequency of sound wave,
- speed of the sound source,
- original speed of sound wave from the source,
<u>According to the Doppler's effect:</u>
The sound is reflected from the wall and the source is moving towards the wall and observer is also riding the same source.
The velocity of the observer, 
Weight tending to shear the pin is
W = 24.0 N
The shear area of the pin is
A = (π/4)*(2.0 x 10⁻³ m)² = 3.1416 x 10⁻⁶ m².
The shear stress is
τ = (24.0 N)/(3.1416 x 10⁻⁶ m²)
= 7.64 x 10⁶ Pa
= 7.64 MPa
Answer: 7.64 Mpa
They differ because they are transverse wave. That is their direction of travel is perpendicular to its vibrations.
