Black hole

-
Black hole is a region of spacetime that pocess such kinds of gravitational pole where nothing can escape from it, even particles and electromagnetic wave.  General theory of relativity by Albert Einstein can give an idea of creating black hole. According to  general theory of relativity sufficient amount of compact mass can form spacetime that leads to form black hole. Black hole may be in three types. Micro types, stellar massive and supermassive.  There consider of a boundary of a black hole, that is called event horizon. Event horizon is such kinds of boundary region of black hole from where no escape is possible. Black hole may be compared with the nature of black body, because like black body, black hole do not reflects light. Simply, it is said that what a things matter or light fall into black hole have no chance of return back.  In quantum field theorem it have that event horizon can emite a radiation which is called Hawking radiation . How black...

Adaption means something gain and adapt. With the stress of environment any change of biological structure and function of life in order to cope with the environment as well as overall survival need satisfaction is termed as biological adaption. A very common adaption we may be familiar with that is immunity. If anyone at anytime in his life infected by specific types of microorganism, body produces antibody against such types of microorganism for further protection. In this case the infected people adapted immunity. Adaption exactly grows for the surrounding effect that enables animals and plants for future protection of affects by these effects. The creosote bush is a desert plant that adapted to produce toxins in order to prevent of growing up of other plants near by it. This adaption of creosote bush in desert happens due to competition for nutrients. Creosote bush does want of increasing the competitor of nutrient. May be birds are such kinds of animal that may illustrate as a go...

Centripetal force

-
Within nucleus electron revolves surrounding nucleus is not collapse even, not go far from nucleus. It is nothing but a result of electrostatic force. Electrostatic force is a combination of two forces opposite direction. These are centripetal force electron direction toward centre and centrifugal force which is directed opposite of centre. According to Rutherford atomic model, both forces are equal and opposite direction within an electron. Centripetal force Directed toward the centre of atom. Any forces directed toward centre is centripetal force. Centripetal force are always found in circularmotion. When any object moves circularly the centripetal force act towards centre of the circular path along with radius of the circle. The force is always orthogonal and fixed to the centre of the curvature. Gravity is a best example of centripetal force. Issac Newton says that it always drawn object. In Newtonian classical mechanics, Centripetal force causes due to orbits of ast...
