What is cell
What is cell class 9 science What is cell: A cell is the fundamental unit of life in all living organisms. It is the smallest structural and functional unit capable of carrying out life processes. It is like a tiny, self-contained “factory” with various components working together to sustain life. Cells are two main types:…
What are isotopes
What are isotopes class 9 science What are isotopes: They have the same number of protons but a different number of neutrons in their atomic nuclei. This means isotopes of an element share the same atomic number but have different mass numbers. For example, hydrogen has three common isotopes: Protium (¹H): 1 proton and no…
Atomic mass
Atomic mass class 9 science Atomic mass refers to the mass of a single atom, and it’s primarily determined by the combined mass of protons and neutrons in an atom’s nucleus (since electrons have negligible mass in comparison). It is measured in atomic mass units (amu). The atomic mass is often close to the mass…

Virtual image
Virtual image class 10 science An image that forms when the light rays appear to come from a certain point but don’t actually converge there. Instead, the light rays diverge after interacting with an optical system, like a mirror or lens, and our brain perceives them as originating from a point behind the system.
Electromagnet
Electromagnet class 10 science a type of magnet in which the magnetic field is produced by an electric current. It’s essentially made of a coil of wire and becomes magnetized only when electricity flows through it. The strength of the magnetic field can be adjusted by: Applications Electric Motors and Generators: Used in machines that…
Heating effect of current
Heating effect of current: The heating effect of current is a phenomenon where electrical energy is converted into heat energy when an electric current flows through a conductor. This happens due to the resistance in the conductor, which opposes the flow of current. The electrons moving through the conductor collide with its atoms, transferring energy…
