D.sound insulators prevent from being transmitted better than elastic solids
Explanation:
The correct option from the given choices is that, sound insulators prevent sound from being transmitted better than elastic solids.
Sound is a form of wave that transmits energy from one point to another.
This wave form is a longitudinal wave in nature.
During the propagation of sound, it requires a material medium to move.
Sound insulators are special materials designed not to transmit sound energy.
Such materials cuts off sound. They are better than elastic solids in preventing sound transmission.

Answer:
<h2>the great size or extent of something!</h2>
KE = 1/2mv²
= 1/2(20 kg)(2m/s²)
= 1/2(20)(4)
= 1/2 (80)
KE = 40 J
hope this helps :)
