Answer:
<em>Sonar can be used to measure the depth of the seabed or the distance of any object, animal or a man-made vessel any other objects </em>
Explanation:
- A sound wave or sound pulse is projected into the water.
- If any object tends to come in the way of the pulse, an echo is produced or the signal is reflected back.
- A transducer measures the strength of this signal and hence determines the depth of the object or the sea.
This is much better way of measuring distances under the sea since light alone is not able to pierce through the ocean after a certain distance.
A powerful sonar blast can help in taking multiple measurements at a time, while even a laser will find it difficult to reach below 3 km of depth.

Hello!
In this case, since the molarity is defined as moles of solute divided by liters of solution, since we have phenol with a molar mass of 94.12 g/mol, we can first compute the moles in 1.5 g of phenol:
Next, since 1000 mL = 1 L, we notice that the volume of the solution is 0.100 L and therefore, the molarity of such solution turns out:
Best regards!
