Transverse waves have motion perpendicular to velocity, while longitudinal waves have motion parallel to velocity.
Explanation:
The correct option of all is that transverse waves have motion perpendicular to velocity while longitudinal waves have motion parallel to velocity.
A wave is a disturbance that transmits energy from one point to another. There several types of waves like sound, electromagnetic , ocean waves etc.
- Waves can be classified as either longitudinal or transverse waves based on the direction through which they are propagated.
- Longitudinal waves are waves propagated parallel to the source of velocity.
- An example is sound waves and seismic p-waves.
- They have series of rarefaction and compression along their path.
- Transverse waves are propagated perpendicular to their source.
- An example is electromagnetic waves in which electrical and magnetic fields vibrates perpendicularly.

Explanation:
Alkenes undergo hydrogenation to give the corresponding alkanes. Where the structure of the original alkene is unknown, we can deduce the structure of the alkene from the structure of the products obtained when it undergoes various chemical reactions.
Now, the fact that we obtained 2-methylhexane upon hydrogenation and the two compounds had different heats of hydrogenation means that the two compounds were geometric isomers. The original compounds must have been cis-2-methyl-3-hexene and trans-2-methyl-3-hexene.
When reacted with HCl, the same compound C7H15Cl is formed because the stereo chemistry is removed.
However, we know that the trans isomer is more stable than the cis isomer hence the cis isomer always has a higher heat of hydrogenation than the trans isomer. Thus X is cis-2-methyl-3-hexene.
Answer:
Matter is anything that has mass and takes up space. Matter can change form through physical and chemical changes, but through any of these changes, matter is conserved. The same amount of matter exists before and after the change none is created or destroyed.
