If v stands for velocity of sound, E is elasticity and d the density, then find x in the equation v = $\left(\frac{d}{E}\right)^x$
Answer & explanation
Correct answer: option 4
V = $\left(\frac{d}{E}\right)^x$
$LT^{-1}=\frac{(ML^{-3})^x}{(MLT^{-2}/L^2)^x}$
LT-1 = L-3x+x T2x
-1 = 2x
x = $-\frac{1}{2}$
