Also, the chemistry-expert team is well aware of the tricky chapters and the difficult concepts that are faced by chemistry students. Therefore, answers to all important questions in the CBSE, ISC chemistry curriculum have been provided while keeping the needs of the student in mind.
PHYSICS

Physics?
Physics is one of the branches of Science and also the most fundamental scientific disciplines. It also say that physics is the father of Science. Physics helps in understanding everyday activities such as answering questions like why rainbow form, how we get energy, how plants respire, why the tap water is warn in winter and cool in summer, etc.
From the above-mentioned examples, it becomes clear that Physics concentrates in explaining the behavior of the human, universe, force, and matter and their effects. Physics has helped in developing new technologies and in many inventions in universe.
Physics as a subject is further divided into branches which include Modern Physics, Classical mechanics, Astrophysics, Nuclear Physics, Electromagnetism, and Optics. These branches are further divided into sub-topics and most of these topics are covered in school syllabus.
Class 11 includes concepts like Units and measurements, Kinematics, Gravitation, Oscillation and Waves, Thermodynamics, Laws of Motion, Work, Power, Energy, and Particle movement.
Class 12 includes concepts such as Magnetism, Electromagnetism, Optics, Current electricity, Electrostatics, Dual nature of radiation, and Electronic devices.
We know that all these concepts have major questions that are covered in textbooks which are either descriptive or objective. Here, at our students will find questions that are descriptive as well as concept based. Questions explained here include examples, problems, properties, definitions etc.
