Gravitational force increases as the mass of objects increases.

The theory applies to all objects in the universe

Gravitational force increases as the distance between objects decreases.

Step-by-step explanation:

Newton's theory of universal gravitation states that every object with mass exerts a gravitational force on every other object with mass.

This force is always attractive in nature, and the magnitude of the force is given by:

$F=\frac{Gm_1m_2}{r^2}$

where

G is the gravitational cosntant

m1, m2 are the two masses

r is the separation between the two masses

We see that the gravitational force is directly proportional to the product of the masses and inversely proportional to the square of their distance.

Therefore, the following statements are correct:

Gravitational force increases as the mass of objects increases.

The theory applies to all objects in the universe

Gravitational force increases as the distance between objects decreases.

While the others are wrong:

The theory applies only to objects on Earth. --> false, the theory applies on every object

Gravitational force increases as mass of objects decreases --> false, the force decreases as the masses decrease

Gravitational force increases as the distance between objects increases --> false, the force decreases as the distance increases

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

$m\angle qrt=156^o$

$m\angle qst=156^o$

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.
