1. V = IR
You rearrange it to make I the subject by dividing both sides by R. You get:
I = V / R
I = 10 / 50
= 0.2 A
2. Q = It
Charge = 0.2 x 2
Charge = 0.4 C
Answer:
Explanation:
As with all atoms known, electrons moves in discrete energy levels round a well defined orbit.
Protons are restricted to the nucleus of an atom. They occupy this small and massive position along with the neutrons.
Metals, have a large dense cloud of electrons.
- Every atom is made up of three fundamental particles.
- Protons, neutrons and electrons are these particles.
- Protons are positively charged and they occupy the tiny nucleus. Neutrons are found in the nucleus with them. They do not carry any charge.
- It is correct to infer their position as being fixed.
- Electrons occupies the bulk of the volume of the atom.
- They orbit round the tiny nucleus.
Therefore, it is safe to conclude that in metal conductors, electrons move but protons do not just like in every other atom.
A scientific law is the description of an observed phenomenon. It doesn't explain why the phenomenon exists or what causes it. The explanation of the phenomenon is called a scientific theory. It is misconception that theories turn into laws with enough research.
The matter from the explosion can reach him, hitting him. He should be able to feel that.
