Answer:
Friction force is equal to the coefficient of friction times the normal force.
Explanation:
It does not really matter if the force is side or not. You need to draw a free body diagram, add weight, normal force, friction force and active force. Then see the horizontal and vertical components to calculate what is the normal force.
The the drift velocity of the electrons is determined by atom vibrations in the crystal lattice.
<h3>How to explain the information?</h3>
Assume we could increase the average time between collisions in a typical metal to get to a limit of zero resistance. The free electrons would therefore be continuously accelerated by a constant applied voltage, according to the classical paradigm of conduction. Both the current and the drift speed would gradually pick up over time.
Although it is not the scenario implied by the question, it is possible to switch to zero resistance by using a superconducting wire instead of the usual metal. In this scenario, the maximum current is constrained, the drift velocity of the electrons is determined by atom vibrations in the crystal lattice, and it is difficult to produce a potential difference across the superconductor.

Answer:
Charge quantization is the principle that the charge of any object is an integer multiple of the elementary charge
Answer:
<h3>An object which moves in the negative direction has a negative velocity</h3><h3>If the object is slowing down then its acceleration vector is directed in the opposite direction as </h3><h3>its motion</h3>
