Answer: Electrostatic force of attraction
Explanation: Electrostatic force of attraction is the force of attraction or repulsion between two electrically charged particles at rest. Like charges repel and unlike charges attract each other.
The answer is D obviously as that is unnecessary for the Earth
Answer:
Explanation:
pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.
Answer;
- This statement about matter and its behavior is best classified as a Law.
-It is the Law of Universal Gravitation.
Explanation;
-The Law of Universal Gravitation states that every point mass attracts every other point mass in the universe by a force pointing in a straight line between the centers-of-mass of both points, and this force is proportional to the masses of the objects and inversely proportional to their separation.This attractive force always points inward, from one point to the other.
-The Law applies to all objects with masses, big or small. Two big objects can be considered as point-like masses, if the distance between them is very large compared to their sizes or if they are spherically symmetric.
