Electrification Processes

Electrostatic Induction Electrization: This electrification process is based entirely on the principle of attraction and repulsion, as electrification occurs only when an electrified body (inductor) approaches a neutral (induced) body. The process is divided into three steps: - Firstly, an electrified rod is approached from an initially neutral conductor, by the principle of attraction and repulsion, the free electrons of the armature are attracted / repelled depending on the signal of the inductor charge.

Uniform movement

When a piece of furniture moves at a constant speed, it is said to be in a uniform motion (MU). Particularly, in the case that it travels at a constant velocity in a straight trajectory, there is a uniform rectilinear movement. An important observation is that when moving at a constant speed, the instantaneous velocity of this body will be equal to the average velocity, since there will be no variation in velocity at any moment of the course.

Superficial dilation

This form of dilation consists of a case where there is linear dilation in two dimensions. Consider, for example, a square piece of sides that is heated at a temperature so that it is increased in size, but as there is equal expansion for both directions of the piece, it remains square but has sides.

Electrostatic Issues

2. Three electrically charged particles are placed on a side equilateral triangle d = 40cm as shown below. What is the modulus of force and an outline of the electric force vector acting on charge 3? To calculate the modulus of force acting on charge 3 we must first calculate separately the influence that loads 1 and 2 have on it, and by both calculate the resulting force.

Magnetic Induction Applications

The main application of magnetic or electromagnetic induction is its use in obtaining energy. Currently all power plants use induction studies as a way of working as it is an efficient way and has several ways to be put into practice. Another great use of this branch of physics is in the development of transformers and self-transformers, which are increasingly improved and their use is already fundamental in almost all major industries.

Contradictions of classical physics to the photoelectric effect

Of the items listed in the previous topic, the only one that conforms to classical electromagnetic theory is that if we set the frequency and ddp, the electric current will be directly proportional to the intensity of the incident light. The item that talks about the existence of a cutoff frequency to which electrons start to emit was not even predicted by the classical theory, so it was conceived based on experimental results only.
