Question

What formula is given for the velocity of a longitudinal pulse in a fluid medium?
Options
A v = √(ρ₀/B)
B v = √(B/ρ₀)
Correct Answer
C v = B * ρ₀
D v = B/ρ₀
Correct Answer

Option B is the correct answer.

Detailed Explanation

On page 13, under the 'Sound Waves' discussion, the text concludes: 'Thus, the velocity of the longitudinal pulse in the medium is v = √(B/ρ₀)'. Here, B is the bulk modulus and ρ₀ is the undisturbed density.

Hint

Find the derivation for the speed of sound in a fluid, specifically the final formula.
