(i) The average binding energy/nucleon for light nuclei like 1 H 1 , 1 H 2 , 1 H 3 is small. (ii) For mass numbers ranging from two to twenty, the sharply defined peaks correspond to nuclei, which are relatively more stable than the neighborhood nuclei. (iii) The binding energy curve has a bro..

The earth's magnetic field has an axis which is inclined 20 o west of the axis of rotation of earth. The point where this huge earth's magnet cuts the earth's surface are the magnetic poles. A freely suspended magnet has its north pole pointing towards geographic north; we therefore designate the e..

Every atom consists of a nucleus containing the entire +ve charge. The whole mass of atom is concentrated at this cor..

As a result of two magnetic fields acting at the same place, the resultant field has a special feature. At a particular point, if the compass needle does not point in any particular direction, then there is no net magnetic field at the point. Such a point is called Neutral point or ..

One desirable feature of radio transmission is that it should be carried without wires (i.e.,) radiated into space. At audio frequencies, radiation is not practicable because the efficiency of radiation is poor. However, efficient radiation of electrical energy is possible at high freque..

Wave Optics - Introduction - The branch of physics dealing with the study of optical phenomena is called optics. This can be divided into two categories, ray optics and wave optics. Wave optics describes the connection between waves and rays of light. The wave theory of light was put fort..

>Space-based remote sensing is a new technology. It has high potential for applications in nearly all aspects of resource management. India recognized the potential of this technology quite early. India conducted several remote sensing experiments in the late '60s and '70s using..

Weather Satellites - Scientists who investigate weather phenomenon are called meteorologists. To study a particular feature, may require an observation from a larger area. By combining great number of observations and analysing them by computers it is possible to get information about a l..

Specific Heat - From the experiments, we know that the quantity of heat supplied Q is proportional to mass of the substance (m) increase in temperature t (t 2 - t 1 ) Q = S m (t 2 -t 1 )------- (1) S is the constant of proportionality. It is a characteristic feature of the substance and i..

As a result of two magnetic fields acting at the same place, the resultant field has a special feature. At a particular point, if the compass needle does not point in any particular direction, then there is no net magnetic field at the point. Such a point is called Neutral point or the Nu..
