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

When high electrical voltage is applied to a gas, its atoms break up into negatively charged particles (electrons) and positively charged particles. These positively charged particles formed by the removal of electrons from the gas atoms are called positive rays. ..

Types of Elements On the basis of electronic configuration, the elements of the periodic table are classified into: Noble gases Normal elements Transition elements Inner-transition elements Alkali metals Halogen..

One can easily differentiate between metals and non-metals based on their placement on the Periodic Table of the Elements. Metals occupy the groups on the left of the periodic table. Group IA consists of highly reactive metals called the alkali metals, while group II A elements are called alka..

All living organisms, whether plants or animals, are made up of microscopic units called cells. The cell occupies the same central position in biology as the atom in the physical sciences..

Question: The figure shows the simple pendulum, which starts oscillating from the extreme position A. Show that the speed of the pendulum when it passes the mean position B is where 'h' is the distance through which the bob of the pendulum is displaced from the mean ..

The positive osmotic pressure developed inside a cell as a result of entry of water is called turgor pressure. When the cells are full of water, they are called turgid and when they lose water, they are called flaccid. The root cells become turgid after the absorption of water and this de..

Imagine yourself sitting in a seat while travelling in a moving train. You observe no change in position with respect to the window. There is change of scene when you view through the window. The change of scene indicates that the train is movi..

Tissues and organs in a body must be supported and held in position. This function is performed by connective tissue, which binds organs and tissues together. They are of four type..

Metals are very reactive. Metals tend to loose electrons easily and form positively charged ion..
