Translation of question

A ship is used to measure the depth of the sea using sound devices. A sound was fired at the bottom of the water and five seconds later there was a bounce. If the speed of sound in the water is 1500 m / s, then the depth of the water is

3750 m

Explanation:

For sound to bounch back and be heard, this phenomenon is echo. Therefore, the distance traveled is 2d. Considering that speed is distance per unit time, expressed as s=d/t where d is distance, t is time and s is speed, in this case we say s=2d/t. Making d the subject of the formula then d=0.5st

Given 5 s as time and 1500 m/s as speed, we deduce that d=0.5*1500*5=3750 m

hi there if you are asking for conformation that wavelingth is the correct answer is wrong it is the answer is frequency. : )

i hope this you out, have a wonderful day

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
