According to the law of universal gravitation, as mass increases, gravity 1.__________ . As distance increases, gravity 2.______
lys-0071 [83]

Answer : (1) The correct option is, (A) increases

(2) The correct option is, (C) Decreases

Explanation :

Gravitational force : It is defined as the gravitational force is directly proportional to the product of the masses of the two object and an inversely proportional to the square of the distance between the two object.

F=G\frac{Mm}{r^2}

where,

F = gravitational force or gravity

M and m = mass of two object

r = distance between the two object

G = gravitational constant

When the mass of an object increases then the gravitational force or gravity is increases because gravitational force is directly proportional to the mass of an object.

When the distance between the two object increases then the gravitational force or gravity is decreases because gravitational force is inversely proportional to the distance between the two object.

Hence, (1) As mass increases, gravity increases. (2) As distance increases, gravity decreases.

Artyom0805 [142]

If a drug slows down central nervous system activity while increasing the activity of the main inhibitory neurotransmitter in the brain, then it is most likely to be a Depressant.

<h3>How do neurotransmitters work and what are they?</h3>

Chemical messengers are called neurotransmitters to facilitate communication between nerve cells. Serotonin, dopamine, glutamate, and acetylcholine are a few of them. Numerous processes are controlled by neurotransmitters, including mood, sleep-wake cycles, and appetite.

<h3>DEPRESSANTS</h3>

These medications, which are sometimes known as "downers," are available as liquid or colored pills and capsules. As they are intended to lessen the symptoms of mental illness, some medications in this class, including Zyprexa, Seroquel, and Haldol, are referred to as "major tranquilizers" or "antipsychotics." Xanax, Klonopin, Halcion, and Librium are examples of depressants that are frequently referred to as "benzos" (short for benzodiazepines).

Allushta [10]

Answer:

Lunar Eclipse: The moon moves in an orbit around Earth, and at the same time, Earth orbits the sun. Sometimes Earth moves between the sun and the moon. When this happens, Earth blocks the sunlight that normally is reflected by the moon. (This sunlight is what causes the moon to shine.)
