Answer:
AB = 16 Units
Explanation:
In the given figure, CD is the diameter and AB is the chord of the circle.
Since, diameter of the circle bisects the chord at right angle.
Therefore, AE = 1/2 AB
Or AB = 2AE...(1)
Let the center of the circle be given by O. Join OA.
OA = OD = 10 (Radii of same circle)
Triangle OAE is right triangle.
Now, by Pythagoras theorem:
There are different kinds of functional group. The answer to the functional group, is below.
- (OH) Alcohol is one of the most polar and may act as a weak acid
- (COOH) Carboxylic acid serves as the acid.
- (C=O) Aldehyde: can be an isomer of a chemical ketone
- (S-H) Thiol usually transform to a disulfide bond
- (NH2) Amine serves to be the base of chemical compounds
- (PO4) Organic phosphate carries a negatively charged atom.
