A person standing between two vertical cliffs produces a sound. Two successive echoes are heard at 4 s and 6 s. Calculate the distance between the cliffs. (Speed of sound in air = 320 m `s^(-1)`)

Text Solution

AI Generated Solution

To solve the problem of calculating the distance between two cliffs based on the time taken for echoes to return, we can follow these steps: ### Step 1: Understand the Problem A person standing between two cliffs produces a sound, and the echoes from the cliffs are heard at two different times: 4 seconds and 6 seconds. We need to calculate the distance between the cliffs. ### Step 2: Define Variables - Let \( d_1 \) be the distance from the person to the first cliff. - Let \( d_2 \) be the distance from the person to the second cliff. ...
