The correct answer is the atomic radius increase because of the higher number of occupied energy levels.
Atomic radius increases when going down a group. The valence electrons hold the higher levels because of the enhancing quantum number (n). As a consequence, the valence electrons get further away from the nucleus with the increase in n. The electron shielding inhibits these outer electrons from getting fascinated towards the nucleus. Therefore, they are held, and the resulting atomic radius is greater.

Answer:
<h2>None</h2>
Explanation:
In the given sequence there is 9 amino acid in which 2 are positively charged amino acid and 7 are neutral amino acid at physiological pH . In each amino amino acid two oppositely charged amino and carboxyl group is present ,where amino is positively charged and proton acceptor and carboxyl is negatively charged and proton donor at physiological pH . pH below neutral cause addition of proton in amino group and makes amino acid positively charged , while pH above neutral cause addition of hydroxide ion in carboxylic group and makes amino acid negatively charged . At pH-4 , all amino acid in the given sequence become positively charge due to addition of proton in the solution ,these protons in the solution binds to amino acid sequence, hence there is no negative charged amino acid in the sequence .
Answer:
Work = 450 J
Explanation:
Force = 90N
Distance = 5m
Work = ?
The relationship between these quantities is given by the equation:
Work = Force * Distance
Work = 90 * 5
Work = 450 J
