An oceanic depth-sounding vessel surveys the ocean bottom with ultrasonic waves that travel 1530 m/s in seawater. How deep is the water directly below the vessel if the time delay of the echo to the ocean floor and back is 6 s?
(sound speed)* (echo time) = 2 * depth
depth = (sound speed)*(echo time)/2
= 1530 m/s * 6 s * (1/2)= 4590 m
to all these people answering in 2019, this hooman here has probably forgotten all about this, after all, its been 14 years.
Answer:
4590m
yeah all most 15 years
i got the same question so this actually helping me thanks
To determine the depth of the water directly below the vessel, we can use the formula:
depth = (sound speed) * (echo time) / 2
In this case, the sound speed in seawater is given as 1530 m/s, and the echo time is given as 6 s. Plugging in these values:
depth = 1530 m/s * 6 s / 2
= 9180 m / 2
= 4590 m
Therefore, the depth of the water directly below the vessel is 4590 meters.
