A. Cold water increases the speed of sound

B. Warm water decreases the speed of sound.

C. Low water pressure increases the speed of sound.

D. High water pressure increases the speed of sound.

Answer 1

Answer:

D. high water pressure increases the speed of sound

Explanation:

Answer 2

Answer:

The answer is D. High water pressure increases the speed of sound.

Explanation:

Due to the characteristics of seawater, the speed of sound propagation changes according to variations in temperature, salinity and pressure. The higher these water characteristics are, the higher their speed will be. if the pressure rises 10 atmospheres, when lowering 100 meters deep, the sound registers 1.8 meters per second of ascent.
