Question

$\huge \mathbb \color{green}{\underline{\underline{Question }}} :$
An observer stand at certain distance away from the Cliff and produce loud sound. hehe hear the echo of the sound after 1.8 s. Calculate the distance between the Cliff and the observer, if the velocity of sound in air is 340 m/s .​

Answer 1

Distance of an observer from the Cliff ,

$\large \sf \color{red}{d \ = \ 306m}$

$\huge \sf \color{purple}{\underline{\underline{Solution }}} :$

Here,

$\bigstar$ Velocity of sound in air, v = 304 m/s

$\bigstar$ Time of echo, t = 1.8 s

$\large \color{green}{\boxed{\sf d = \frac{vt}{2}}} \\ \\ \implies d = \frac{340×1.8}{2} \\ \\ \implies d = 306 m$

Distance from of the observed from the Cliff is 306 m .
