multiple choice question
the average velocity of sound in seawater is ______ m/s as opposed to 334 m/s in dry air at 20℃
o 2500
o 1500
o 800
o 100

Explanation:

Sound travels faster in seawater than in dry - air at 20°C due to the higher density and elastic properties of seawater. The average velocity of sound in seawater is approximately 1500 m/s.
