Question

A strong sound signal is sent from a ship towards the bottom of the sea. It is received back after $1second$. What Is the depth of the sea? (Speed of sound in water= $1450m/s$)

Answer 1

Step 1 Given data,

Speed of sound in water is $v=1450m/s$
Time taken to receive the signal is $=1s$
So, Time taken for the sound to reach the bottom of the sea is $t=\frac{1s}{2}=0.5s$

Step 2: Finding the depth of the sea (d),

$Depthofthesea\left(d\right)=Speedofsoundinwater\left(v\right)\times Time\left(t\right)=1450m/s\times 0.5s=725m$
Hence, the depth of the sea = $725m$
