An amino acid A, isolated from the acid-catalyzed hydrolysis of a peptide antibiotic, gave a positive ninhydrin test and had a s
pecific optical rotation (HCl solution) of 37.5 mL/(g·dm). Compound A was not identical to any of the 20 essential amino acids. The isoelectric point of compound A was found to be 9.4. Compound A can be prepared by the reaction of L-glutamine with Br2 in NaOH followed by acidification. Suggest a structure for A.

Answer:
v = 450 m/s
Explanation:
Given data:
Frequency = 75 Hz
Wavelength = 6 m
Velocity = ?
Solution:
Velocity is the product of frequency and wavelength.
v = f × λ
v = 75 Hz × 6 m
Hz = s⁻¹
v = 75 s⁻¹ × 6 m
v = 450 m/s
