Answer:
two positively charged objects
Explanation:
Increase the concentration of the dissolved reactants
Increase the temperature of the reactants
Add a catalyst such as iron to the reaction
The pressure of the reacting gases can be increased
The relationship between gravitational force and distance of separation is an "inverse relationship".
<u>Explanation:</u>
Gravitational force has been explained by "Newton's Universal Law of Gravitation" which says "In this universe every single particle attract every other particle with a force which directly proportional to the product of their masses while inversely proportional to the square of the distance in between them".
The gravitational force is inversely proportional to square of distance because as the distance between the objects with masses increases the force decreases. The gravitational force between any two objects with masses can be understood by given formula:
Here the F is gravitational force,
G is the gravitational constant =
are the masses of the two objects
d is the distance between two objects.
Answer: radio and television
Satellite orbits with an East-West orientation are best used
for communication purposes. The satellite orbit should always be suited for its
purpose. Radio and television are powered by numerous satellites rotating the
Earth from east to west.
