Question

What is the difference between a declarative sentence and an interrogative sentence?

A. A declarative sentence contains a relative clause; an interrogative sentence contains an adverbial clause.
B. A declarative sentence is formed by joining two independent clauses; an interrogative sentence is formed by joining a dependent clause and an independent clause.
C. A declarative sentence has a single subject and predicate; an interrogative sentence has two or more subjects or predicates.
D. A declarative sentence makes a statement, and an interrogative sentence asks a question.

Answer 1

Explanation:

According to Universal law of gravitation, the force of attraction between 2 bodies is:-

F = (G m1m2)/r2

Where m1m2 = the masses of the two bodies,

r = distance between them

G = gravitational Constant

When the distance is reduced to half i.e. r’ = (1/2) r then,

F’ = (G m1m2)/r2

= (G m1m2)/(r/2)2

= (4 G m1m2)/ (r2) = 4F

Therefore when the distance between the objects is reduced to half, then the force of gravitation increases by four times the original force
