alexandr1967 [171]
In order to answer this question, the units of volume must be consistent. In this problem, we decide the unit m3 to be uniform. Option A is equal to 12 m3, option b is equal to 1.2x10^8/100^3 or 120 m3. Option C is 2.0 x10^4/ 10^3 or 20 m3. Option D is 1.2x10^8/ 1000^3 or 0.12 m3. The greatest volume is option b. 120 m3.

Answer:

O parallel

Explanation:

For longitudinal waves, the direction of wave motion is parallel to the direction of their propagation.

Longitudinal waves are transferred by a series of rarefaction and compressions along their path.

One important longitudinal waves are sound waves and seismic p-waves.

Transverse waves a propagated perpendicular to the direction of their displacement.
