Answer:
A Longitudinal Wave is _____.
D.a wave that the medium is displaced parallel to the direction of the wave, such as a sound wave in the air
Explanation:
Sound : It is the mechanical energy that causes sensation of hearing to the ear.
Sound is produce by the vibrating objects .
Vibration : To and fro motion of the object.
The vibrating motion of particle creates two region of air pressure:
- Compression : A region of high - pressure
- Rarefaction : A region of low- pressure
Hence , Sound wave travels by forming compression and rarefaction.
This disturbance in particles of air is called : Wave
The waves are classified into two parts :
1. Longitudinal wave : These are those waves in which particles of medium travel parallel to the propagation of the wave.They both <u>travel in same direction.</u>
<u>Sound wave </u>is longitudinal wave
2. transverse wave : These are those wave in which particle of medium travel perpendicular to the direction of wave . If particles travel along x-axis then wave along y or z- axis.
example : Light (or electromagnetic wave) is transverse wave

Answer:
Bromobenzoic acid
Explanation:
COOH has higher priority than Br, so the parent name is benzoic acid.
The COOH group is automatically on C1 of the ring, and the other aromatic carbons are numbered sequentially around the ring.
The name of the substituent is joined to that of the parent, and the locant is attached to that with a hyphen.
The generic IUPAC name is bromobenzoic acid.
There are three isomers of benzoic acid — 2-bromobenzoic acid, 3-bromobenzoic acid, and 4-bromobenzoic acid — so you must always specify which one you mean.
