Answer:
Because the force is inversely proportional to the square of the distance
Explanation:
The magnitude of the electrostatic force between two charged particles is given by
where
k is the Coulomb's constant
q1, q2 are the magnitudes of the two charges
d is the distance between the two charges
We observe that the magnitude of the force is inversely proportional to the square of the distance.
Therefore, when the distance changes to
The force will double:
Answer:
9.8 m/s^2
Explanation:
This is a constant that you should memorize
Parabolic Motion<span> of Projectiles. A projectile is an object upon which the only force is gravity. Gravity, being a downward force, causes a projectile to accelerate in the downward direction.
So I would say that the best answer provided is C. a leaf falling from a tree because the downward force of gravity causes the leaf to accelerate in the downward direction</span>
If I'm correct, gold does not tarnish so C.
