For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal<span>. </span>Longitudinal<span> waves are waves in which the motion of the individual particles of the medium is in a direction that is </span>parallel<span> to the direction of energy transport.
Im not sure. but ur welcome. ☺</span>
It is estimated that about 1 ft of snow is equal to 1 inch of rain.
Converting inch to cm
1 inch=2.54 cm
Thus, 1 cm=0.393 inch
2.5 cm of rain will be 0.984 inch
now 1 inch of rain is equal to 1 ft of snow, thus, 0.983 inch of rain will be:
0.983 inch of rain=0.983 ft of snow.
Converting ft to cm:
1 ft =30.48 cm
Thus,
0.983 ft= 29.96 cm
Thus, 2.5 cm of rain= 29.96 cm of snow.
The formula unit equation for the given reaction occurring in water is
CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).
<h3>What is chemical reaction?</h3>
Chemical reactions are those reaction in which reactant molecules react with each other for the formation of product.
When calcium sulfide reacts with iron (II) bromide for the formation of iron(II) sulfide and calcium bromide will be represented through the following equation:
CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq)
Above reaction best explains the formula unit of given reaction as all valency of atoms are satisfied there.
Hence, the required formula unit is CaS(aq) + FeBr₂(s) → FeS(s) + CaBr₂(aq).

No the law of cross cutting relates to all somewhat horizontal. The law of cross cutting is the logical assumption that a magma protrusion that cuts through horizontal layers at a diagonal or vertical is younger than the layers that it cuts through.
Sedimentary rocks are most often found in horizontal or near horizontal layers or strata. Therefore cross cutting can be used most often in the relative dating of sedimentary rocks.
However lava flows also form horizontal layers of rock. Pumice ash can be laid down in horizontal layers. A magma protrusion can also be used to relative date igneous layers of rock
