Question

A percent reduce the sound with the siren near Cliff and heard ecos after 6 second. Find the distance of the siren from the Cliff is velocity of sound waves produce in 330m/s? ​

Answer 1

ANSWER

Time taken by eco to be heard= 2d/v =6s

Velocity of sound waves = 330m/s

2d = v×t = 330×6= 1980m

$d = \frac{1980}{2}$

= 990m

Therefore, the distance of the siren from the Cliff is 990m.

Answer 2

Time taken by eco to be heard= 2d/v =6s

Velocity of sound waves = 330m/s

2d = v×t = 330×6= 1980m

$d = \frac{1980}{2}$

= 990m

Therefore, the distance of the siren from the Cliff is 990m.
