Charging of Insulators
Since charge cannot flow through insulators, neither conduction nor induction can be used to charge, insulators, so in order to charge an insulator friction is used. Whenever an insulator is rubbed against a body exchange of electrons takes place between the two. This results in appearance of equal and opposite charges on the insulator and the other body. Thus the insulator is charged.
For example rubbing of plastic with fur, silk with glass causes charging of these things.

Reynolds Number
Last modified on:3 years agoReading Time:10MinutesWhat is Reynolds Number? The Reynolds number (Re) is a dimensionless parameter used in fluid mechanics to characterize the flow of a fluid (liquid or gas) around an object or through a conduit. It relates the inertial forces to the viscous forces in the fluid and helps determine the type of…

How do Organisms Reproduce
Last modified on:5 years agoReading Time:22MinutesHow do Organisms Reproduce Reproduction is the process by which living organisms produce new individuals similar to themselves. It ensures continuity of life on earth. Nucleus of the cell contains DNA (Deoxyribose Nucleic Acid) which is the heredity material. DNA replicates and forms new cells causing variation. So, these new cells…
