Answer:
C. tiny particles called charges flowing through the wires.
Explanation:
<h3> Hello!</h3>
An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space. It is measured as the net rate of flow of electric charge through a surface or into a control volume.
Hope it helps!
The electrostatic force between two charges is given by

where
k is the Coulomb's constant
q1 and q2 are the two charges
r is their separation
In this problem, the two charges are identical, so we can call them q1=q2=q, and the formula becomes

Since we know the magnitude of the force and the separation between the two charges, we can re-arrange the equation to find the value of each charge:
Answer: The given statement is True.
The proliferation of photosynthetic planktons results in harmful algal blooms. Due to this, the surface of the water body gets completely covered with algal bloom. This blocks the sunlight as it can not penetrate the water. Due to this, photosynthetic planktons are no more able to perform photosynthesis. This ultimately ends up depleting all oxygen from the body of water.
Thus, the given statement is true.
Answer:
I think its B
Explanation:
because "This means that when you rubbed the plastic comb along your hair, your hair resisted the movement of the comb and slowed it down. The friction between two surfaces can cause electrons to be transferred from one surface to the other."
