line position and staff position

If a reference line on a rigid body rotates through an angle , a point within the body at a position 'r' from the rotation axis moves a distance 's' along a circular arc where 's' is given by ..

When the body is at position C, its height above the ground may be regarded as zero. Therefore, potential energy of the body = 0. If v c is the velocity with which the body touches the ground, then v c 2 - 0 = 2gh v c 2 = 2gh Total energy of the body = mgh From the above illust..

If the velocity of an object increases then the object is said to be moving with positive acceleration...

Haloalkanes with three or more carbon atoms exhibit position isomerism in which the isomers differ in the position of halogen atom. For example, C 3 H 7 I has two position isomers:..

A vector which gives the position of a point with reference to the origin of the coordinate system is called position vector. The figure above illustrates the position vector of a particle moving in the X-Y plane. Let the particle be at P at any instant of t..

This isomerism arises due to the difference in the position of the same functional group or the same substituent while the arrangement of carbon atoms remains same. For example, Chloropropane (C 3 H 7 Cl) can have two positional isomers given below. Butene (C 4 H..

It is a positive inter specific interaction in which both the partners are mutually benefitted and increase the chance of their survival. However, the interaction is not obligatory for their survival as both can live without this interactio..

The position of hydrogen was not correctly defined. It was placed in Group I although its properties resembled both the Group I elements (the alkali metals) and the group VII elements (the halogens..

Positive Interactions amongst different species in a community - Interaction Effect on species A Effect on species B Nature of Interaction A. Positive Scavenging (+) (Nil) Beneficial to scavenger, who feeds on flesh or dead organisms Commensalism (+) (Nil) One is beneficial, oth..

Division: Angiospermae Class: Dicotyledonae Subclass: Gamopetalae Series: Inferae Order: Asterales Family: Asteraceae (=compositae) Commonly known as sunflower family. It is the largest family in dicots. It includes about 900 genera and 13,000 species. It has a cosmopolitan distribution. There are ..
