Heya user☺☺
All options are wrong here.
The correct answer is..
Work/Time.
Hope this will help☺☺
A charge of 12 c passes through an electroplating apparatus in 2.0 min, then the average current is 0.1 ampere.
<h3>What is an electric charge?</h3>
Charged material experiences a force when it is exposed to an electromagnetic field due to the physical property of electric charge. You can have a positive or negative electric charge.
Electric current is defined as the charge per unit of time.
The mathematical relation between current and the electric charge
I =Q/T
where I is the current flowing
Q is the total electric charge
T is the time period for which the current is flowing
As given in the problem A charge of 12 c passes through an electroplating apparatus in 2.0 min
Let us first convert the time period of minutes into seconds
1 min = 60 seconds
2 min = 2*60 seconds
=120 seconds
By using the above relation between electric current and electric charge
and by substituting the respective values of the charge and the time period
I =Q/T
I = 12c/120 seconds
I = 0.1 Ampere
Thus, the average current flowing through the apparatus would be 0.1 Ampere.

Answer:
Thermal energy always flows from the warmer object to the colder object. This causes your hand to get cold, while the ice absorbs your heat and melts.
Remember that like charges repel each other. That is, positive repels positive and negative repels negative. Similar to how the north poles of magnets repel each other and south poles repel. However, at the atomic scale, protons, which have positive charge, are more influenced by the "Strong Force," which binds them close together. If they were to be separated ever so slightly, then the electromagnetic force would take over and they would repel each other like you'd expect.
Neutrons are also held together via the Strong Force, but don't have a charge so when separated, don't have an electromagnetic force pushing them away from each other.
However, electrons act differently. There is no "Strong Force" just the electromagnetic force. So, they keep a great distance from each other.
So in an atom, protons and neutrons stay close to each other, taking up little volume, while electrons take up a lot of volume.
BTW, the reason why electrons and protons act differently when they are close together is because protons are made up of smaller particles the carry this Strong Force. For electrons, there is no smaller constituent. And therefore, all you have is the electromagnetic force to influence it. That's it.
Hope that helps.
