Aresearch vessel is mapping the bottom of the ocean using sonar. it emits a short sound pulse called "ping" downward. the frequency of the sound is 5600 hz. in water sound propagates at a speed of 1474 m/s. the sound pulse is then reflected back from the bottom of the ocean and it is detected by the vessel 8.88 s after it was emitted. how deep is the ocean just below the vessel?

The ocean is 6485.6m deep when measured from the vessel

Explanation:

v=1474m/s

t=8.88s

let d represent distance from the vessel to the ocean bottom.

an echo travels a distance equivalent to 2d, that is to and fro after it reflects from the obstacle.

d= 6485.6m

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
