We put in your hands this free app which provides you with a wonderful explanation of physics and chemistry lessons in a simple and easy to understand way. Here we are talking about lessons: successive mechanical waves, periodic mechanical waves, and the propagation of a light wave. The RL electrode and free oscillations in a series RLC circuit, then finally he studied amplitude modulation.
As for chemistry, we will learn the following lessons: the chemical transformations that occur in two directions, then the chemical transformations that occur in two aspects, the equilibrium state of a chemical group, and the chemical transformations associated with acid-base reactions + acid-base titration.
With this application on a set of experiments and bold graphics which in turn prove understanding. This app also contains exercises which help a lot to understand the lesson and contains all the questions that have been asked that could be asked during the baccalaureate exam and each question has a detailed explanation of how to solve it on the exam of the baccalaureate, where there are easy application exercises to install the Dari and others that are difficult to deepen in the lesson. There are also complete combined exercises of two or more lessons, as in the national exams.
Finally, you will find a set of exercises from the national exams, including physics and chemistry (regular session + remedial session), which gives you prior knowledge on how to manage the national exam.
The purpose of the methodology that this app has come out of is to break down the barrier of what is called difficult physics. Therefore, we have presented it in an understandable way to easily earn points, any student who wants to get an honorable point in physics and chemistry, regardless of level, is able to work hard.
