POLYMERS Polymers can be defined as the high molecular mass macromolecules that are formed due to the repetition of the basic unit, monomer. MONOMER The unit molecules that combines with each other to form a polymer. POLYMERISATION The process of formation of polymers by the repeated addition of the monomers …

Breadth First Search is an algorithm for traversing elements from a data structure or searching tree. Visiting each vertex and edge exactly in a well defined order is done in Graph travelers. Traversal of an element in graphically is well defined in searching algorithms. The first traversal in BFS accomplished …

MOTION When a body changes its position continuously with respect to a stationery object, which is taken as a reference point. It can be depicted by this graph: Motion includes both distance and displacement. Distance is a scalar quantity because it has magnitude only. Displacement is a vector quantity because …
