Question

aditi clapped her hands near a cliff and heard the echo after 4 seconds. what is the distance of cliff from her if the speed of sound is taken as 346ms-1

Answer 1

Given

Speed of sound (u)=346 m/s

Time taken for hearing the echo (t)=4s

Now

speed=

time

distance

​

⇒346=

4

distance

​

⇒distance =(346×4)=1384.

Total distance covered by sound is 1384 m

In 4 s, sound has to travel twice the distance between the cliff and aditi.

Therefore, the distance between the cliff and aditi is =

2

1384

​

m=692 m

Distance of cliff from aditi =692 m.

Step-by-step explanation:

my other one is no longer up sowwy for what i didn't do right hope this one is better have a good day hope the best comes to you

Answer 2

We know, speed = distance / time
Here, s = 346 m/s
t = 4 s

Substitute their values,
346 = d/4
d = 346 * 4
d = 1384 m

In short, Your Answer would be 1384 meters

Hope this helps!
