Answer:
2600 m
Explanation:
A fathometer produces a sound wave and then detects the echo. It takes 3.5 seconds for the echo to reach the ship, so that means it takes half the time (1.75 seconds) to reach the ocean floor.
The speed of sound in seawater is approximately 1500 m/s, so the depth of the ocean at that point is:
d = 1500 m/s × 1.75 s
d = 2625 m
Rounding to two significant figures, the depth is approximately 2600 m.
Explanation:
If a person is set to walk on a constant speed regardless of the situations then if the person walks a certain distance with no interruptions in an observed time then her speed can be calculated.
When the same person walking through the room momentarily stops to introduce herself then the average speed of the of the person slows down as it happens with the light wave when passes through glass which is an optically denser medium than the air, but the light wave does not stop anywhere in the medium.
It can be more relevant to the person's speed when she walks wading through the water or the person walks through the sand then the person feels resistance in the sand or in water which reduces her overall speed.
To see which way atmospheric conditions and meteorological phenomena are moving, and how fast.
Also to see whether they were correct yesterday.
because there small elemts like atoms but bigger than atoms we all know that
