Question
The speed of sound can be different depending on which of the following?Question 2Answera.Height above sea levelb.Temperaturec.The lunar phased.How close the medium’s particles are to each othere.The amount of training of the person operating the sound sourcef.a., b., d. g.b., c., d.h.b., c., d.i.a., b., c., d.
Solution
The speed of sound can be affected by:
a. Height above sea level: The speed of sound decreases as we go higher above the sea level because the air becomes less dense.
b. Temperature: The speed of sound increases with an increase in temperature. This is because the particles of the medium move faster at higher temperatures, thus transmitting the sound faster.
d. How close the medium’s particles are to each other: The speed of sound is faster in solids than in liquids, and faster in liquids than in gases. This is because particles are closer together in solids than in liquids, and closer in liquids than in gases, allowing sound to be transmitted faster.
Therefore, the correct answer is f. a., b., d.
