Answer:
the first line
Explanation:
A rarefaction is a region in a longitudinal wave where the particles are furthest apart. ... The region where the medium is compressed is known as a compression and the region where the medium is spread out is known as a rarefaction.
use this picture as a reference:
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.
1. Only particles in the solid state are not in motion 2. The particles of a solid have less energy than gas 3. In a glass of iced tea the sugar in iced tea are the solvent and the water is the solute.
Answer:
True
Explanation:
This is because the Earths ionisphere was distrubed which makes radio communications.
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.
