An oceanic depth-sounding vessel surveys the ocean bottom with ultrasound waves
that travel at 1530 m/s in seawater. The time delay of an echo to the ocean floor
below is 3 seconds. Find the depth of the water.

  • physics - ,

    The sound traveled twice the depth of the water (down and back).

    2*depth=1530m/s*3seconds

  • physics - ,

    From,
    Speed=distance/time
    Where,
    S=1,530m/s, t=3s and d=?
    => d=s*t
    D=1,530*3
    D=4,590m
