Question

How does changing temperature affect the speed of sound in water, and why is this important for certain applications? A) Changing temperature increases the speed of sound in water, which is important for underwater communication. B) Changing temperature decreases the speed of sound in water, which is important for the safety of submarines. C) Changing temperature has no significant effect on the speed of sound in water. D) Changing temperature can either increase or decrease the speed of sound in water, depending on other factors.

Answer 1

Changing temperature decreases the speed of sound in water, which is important for the safety of submarines.

Step-by-step explanation:

The correct answer is B) Changing temperature decreases the speed of sound in water, which is important for the safety of submarines.

When the temperature of water decreases, the speed of sound in water also decreases. This is because cooler water molecules have less kinetic energy, resulting in slower movement and slower transmission of sound waves. This is important for the safety of submarines because their detection and tracking systems depend on accurately estimating the speed of incoming sound waves.
