Answer: depth = 3.75 m
Explanation:
Taken the speed of the sound in sea to be V = 1500 m/s
The time between an echo sounder sending and receiving a pulse is 0.005 s. That is,
Total time T = 0.005
Formula for echo is:
V = 2X/T
Where X = distance covered
Substitute V and T into the formula
1500 = 2X/0.005
Cross multiply
7.5 = 2X
Make X the subject of formula
X = 7.5/2
X = 3.75 m
Therefore, the depth of the sea is 3.75 m
Hey there, the answer is .............................. About 0.7 m/sec^2
<span>
Acceleration is the change in speed / time </span>
<span>Change in speed is 60 m/sec </span>
<span>Time is 1 minute 25 second. Convert that to seconds. </span>
<span>Divide the change in speed by the time in seconds.
About 0.7 m/sec^2
</span><span>So the acceleration is - 60 / 85 = - 0.71 m/s^2
