Question

A marine biologist is working on a research vessel to study whale calls. His recording devices are measuring depths above 1,000 meters. As his vessel travels to cooler waters and begins to measure at greater depths, the marine biologist needs to make adjustments to his monitoring devices. Why is that?
A- from 0 to 1,000 meters, sound travels at a faster speed in cooler water.
B- from 0 to 1,000 meters, sound travels at a slower speed in cooler water.
C- at depths deeper than 1,000 meters so

Answer 1

I believe the answer is B it makes sense it travels slower in colder water its just pure logic in my opinion. but yeah i think the answer is B

Answer 2

Answer:

Option B. The marine biologist needs to make adjustments to his monitoring devices because from 0 to 1.000 meters, sound travels at a slower speed in cooler water.

Explanation:

In water, the higher the temperature of the molecules creates a medium that allows sound to travel faster, in fact, sound travels abut 15 feet per second faster for every 1.8 degrees Fahrenheit  rise in the temperature of water. This is the reason that as the biologist's vessel travels to cooler waters, he needs to make adjustments to his monitoring devices.
