A) 1500 m
B) 1000 m
C) 1531 m
D) 1530 m
Correct Answer: C
Solution :
Let the depth of water be ?d?. Distance travelled by the pulses is going down towards bottom and reflecting upwards to the surface is \[s=2d\] time taken \[t=2s\] Depth of water\[=d=?\] We know, \[s=vt\] \[\Rightarrow \] \[2d=vt\] \[\Rightarrow \] \[d=\frac{vt}{2}\] \[\Rightarrow \] \[d=\frac{1531\times 2}{2}=1531\,m\] \[\therefore \] Depth of water = 1531 m.You need to login to perform this action.
