Question 1A ball of mass 100 g is projected vertically upwards from the ground with a velocity of 49 m/s. At the same time, other identical ball is dropped from a height of 98 m to fall freely along the same path as followed by the first ball. After some time two balls collide and […]

## The flow of charge: definition and explanation

The flow of charge in an electric circuit signifies the existence of electric current in that circuit. We can define electric current as the rate of flow of electric charges (electrons) in a conductor (for example copper or metallic wire). Flow of charge definition The flow of charge is the process of supplying or adding

## Algebraic Identities

In this article, we will look at standard identities as well as some other Algebraic identities. In addition, we will attempt to derive these identities without using the binomial theorem. We’ll also look at some solved examples of problems that use these mathematical identities to solve them. What is an Algebraic Identity An Algebraic identity
