Bangla Note of Physics 2nd paper for HSC
Atom The atom is a basic unit of matter that consists of a dense central nucleus surrounded by a cloud of negatively charged electrons. The atomic nucleus contains a mix of positively charged protons and electrically neutral neutrons (except in the case of hydrogen-1, which is the only stable nuclide with no neutrons). The electrons … Read more

Last Updated: March 19, 2026 at 8:51 pmMath Solution of Electronics Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive interconnection technologies. The nonlinear behaviour of active components and their ability to control electron flows makes amplification of weak signals possible and electronics is widely used in information processing, … Read more

(The word relativity can also be used in the context of an older theory, that of Galilean invariance.) Concepts introduced by the theories of relativity include: Measurements of various quantities are … Read more
