Answer:
TO POWER ELECTRIC GADGETS AND SAVE EARTH FROM POLLUTION
Explanation:
The electrical force between two charges is given by
where
k is the Coulomb's constant
q1 and q2 are the two charges
r is the distance between the two charges
We see that the magnitude of the force is inversely proportional to the square of the distance. Therefore, if the distance is increased to 3 times the original distance:
the magnitude of the force will change as
So, the correct answer is <span>
it will decrease to one-ninth the original force.</span>
Answer:
the total acceleration decreases when a body falls until it reaches the value of zero.
Explanation:
In general, resistive forces always oppose the movement of bodies, when a body falls into the air it is subject to two forces, the gravitational attraction and the resistive force of the air that opposes this movement, this force is proportional to the speed and the size of the body increases its value until it equals the acceleration of gravity and from this moment the body moves with constant speed.
In summary, the total acceleration decreases when a body falls until it reaches the value of zero.
<span>Ocean water conducts electrical current because it contains electrolytes. Electrolytes are good conductors of electricity, and are naturally present in appropriate amounts in bodies of water. However, pure water (without electrolytes or metals) is not a conductor of electricity. </span>
