Distance and Displacement - Suppose a bus starting from a terminus A travels 15000 m to reach terminus B. Then the distance covered by the bus is 15000 m. Now if the bus returns to the terminus A, then what is the distance covered by the bus during the return trip? The distance covered is..

A substitution or displacement reaction is a chemical change in which atoms of one element replace the atoms of another element from the molecules of a compound. For e.g., When an iron knife is dipped in an aqueous solution of copper sulphate, a layer of reddish brown precipitate is fo..
