Question

the time between a clap and its echo froma wall is 0.1 second.If the distance of the wall be 17.5 metere calculaye the speddd of sound
For correct answer I will mark as the brainliest
plssss urgentt​

Answer 1

Answer:

For the sound to come back as an echo, it has to travel double the distance. Therefore, the distance travelled by the sound is 2(17.5 m)=35 m. Speed is the distance travelled per unit time. Therefore, the speed of the sound is 35 m/0.1 sec=350 m/s.

Answer 2

Answer:

hi

Explanation:

GIVEN :-

• d= 17.5m

• t = 0.1sec

Find :-

• v = ?

Calculation :-

=> sound travelled to the wall and back,

=> thus, d + d= 2d

=> since, total distance = 2d

=> As we know that,

=> v = d/t

•put values

=> .°. v = 2×17.5/0.1

=> v = 350m/s

.°.v=350m/s

Therefore, the speed of sound is 350m/s.
