Question

Suppose a fish is located at a depth of 6124m below the base of the streamer and the speed of sound is taken to be 1531 m/s. If the horn is blown at 9:00 am sharp after how many seconds will the fish hear the sound?(height of the streamer is neglected)

Answer 1

Answer:

4s

Explanation:

fish is located at a depth of 6124m below the base of the streamer

speed of sound is taken to be 1531 m/s.

time taken by sound to travel 6124m in water = distance ÷ speed = 6124 ÷ 1531 = 4 s

So, after 4 seconds, the fish will hear the sound.

Answer 2

Answer:

Explanation:

Here,

We have,

Distance where fish located = 6124 m

Speed of sound = 1531 m/s

To Find,

Time taken = ?

We know that,

Time taken = Distance/Speed

Putting all the values, we get

Time taken = Distance/Speed

⇒ Time taken = 6124 m/1531 m/s

⇒ Time taken = 4 seconds

Hence, the time taken fish to hear sound is 4 seconds.
