Answer:
Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive.
Explanation:
The potential difference between the ends of the wire is 37.5 V
Explanation:
We can answer this question by using Ohm's law, which states the relationship between current, resistance and potential difference in a wire:
where
V is the potential difference
R is the resistance
I is the current
For the wire in this problem, we have:
I = 3 A is the current
is the resistance
Solving the equation for V, we find the potential difference:

Idk im not very good at math
According to Newton's 3rd law, the force on the (smaller) moon due to the (larger) earth is "equal in magnitude to, and in the opposite direction from, the force on the earth due to the moon".
<u>Option:</u> C
<u>Explanation:</u>
A force is a push or pull acting on an entity as a consequence of its contact with a particular object. Such two phenomena are called forces of action and reaction, and are the origin of the third law of motion by Newton.
This law states the force of the moon on earth is equal and opposite to the force of earth on the moon. The enticing force operating between a satellite orbiting the earth in a circular path allows the object to accelerate towards earth, but since it maintains its circular orbit, it never gets closer to earth.
