Question

question 13 of 20 : select the best answer for the question. 13. which of the following statements is true of sound transmission through various mediums? a. inelastic materials conduct sound better than elastic solids. b. sound insulators prevent sound from being transmitted better than elastic solids. c. gases conduct sound better than liquids. d. elastic solids prevent sound from being transmitted better than liquids. mark for review (will be highlighted on the review page)

Explanation:

To solve this, we analyze each option based on sound transmission principles:

• Option A: Elastic solids (not inelastic) are better at conducting sound due to closer particle arrangement and faster vibration transfer. Eliminate A.
• Option B: Sound insulators (e.g., materials with air pockets) reduce sound transmission. Elastic solids (like metals) are good conductors. So insulators prevent transmission better than elastic solids. This is correct.
• Option C: Liquids conduct sound better than gases because liquid particles are closer. Eliminate C.
• Option D: Elastic solids conduct sound better than liquids (e.g., sound travels faster in metal than water). Eliminate D.

Answer:

B. Sound insulators prevent sound from being transmitted better than elastic solids.
