Question

If Young's modulus of the material of a is Y and density is ρ then time taken by sound wave to travel l length from bottom is (A) l√(ρ/Y) (B) l√(Y/ρ) (C) (l/l])√(Y/ρ) (D) (l/l)√(ρ/Y)

t = (Distance/speed) = (l/√(Y)P)

Q. If Young's modulus of the material of a is Y and density is $ρ$ then time taken by sound wave to travel l length from bottom is

$l \frac{ρ}{Y}$

$l \frac{Y}{ρ}$

$\frac{l}{l ]} \frac{Y}{ρ}$

$\frac{l}{l} \frac{ρ}{Y}$

$t = \frac{D i s t an ce}{s p ee d} = \frac{l}{\frac{Y}{P}}$
