Newton's law of motions
Newton, the father of physics established the laws of motion in his book "principia" in 1667.
Newton's first law of motion : Every body maintains its initial state of rest or motion with uniform speed on a straight line unless an external force acts on it. First law is also called law of Galileo or law of inertia.
Newton's second law of motion : The rate of change in momentum of a body is directly proportional to the applied force on the body and takes place in the direction of force. Newton's second law gives the magnitude of force.
Newton's third law of motion : To every action, there is an equal and opposite teaction.

Fiscal System and Fiscal Policy
Fiscal System : It refers to the management of revenue and capital expenditure finances by the state. Hence, fiscal system includes budgetary activities of the government that is revenue raising, borrowing and spending activities.
Fiscal Policy : Fiscal Policy refers to the use of taxation, public expenditure and the management of public debt in order to achieve certain specified objectives.

What is Cell?
Cell is the basic structural and functional unit of life. The word 'cell' was first coined by British scientist Robert Hook in the year 1665. The smallest cell is Mycoplasma gallisepticum. The longest cell is Neuron. The biggest cell is egg of Ostrich.
Schilden and Schwan established cell theory in the year 1838-39. Features of the cell theory :
(i) All organism are composed of cell
(ii) Body of every organism is made of cell
(iii) Each cell arises from pre-existing cell
(iv) Every organism starts its life from single cell

Evaporation
Evaporation : The process of conversion of a liquid into its vapours at room temperature is called evaporation. Evaporation causes cooling.
Actually, during evaporation, the molecules having higher kinetic energy escape from the surface of the liquid. Therefore cooling takes place during evaporation because of temperature of liquid is directly proportional to average kinetic energy.
Evaporation is affected by following factors :
(i) Nature of liquid
(ii) Temperature
(iii) Surface area

Russian State Library
The "Russian State Library" is the national library of Russia, located in Moscow. It is the largest in the country and the third largest in the world for its collection of books (17.5 million). It was named the V. I. Lenin State Library of the USSR from 1925 until it was renamed in 1992 as the Russian State Library.
The library has over 275 km of shelves with more than 43 million items, including over 17 million books and serial volumes, 13 million journals, 350 thousand music scores and sound records, 150,000 maps and others. There are items in 247 languages of the world, the foreign part representing about 29 percent of the entire collection.
Between 1922 and 1991 at least one copy of every book published in the USSR was deposited with the library, a practice which continues in a similar method today, with the library designated by law as a place to hold a "mandatory" copy of every publication issued in Russia.

Sound Wave
Sound Wave : Sound waves are longitudinal mechanical wave. According to their frequency range, longitudinal mechanical waves are divided into the following categories :
(1) Audible or Sound Waves : The longitudinal mechanical waves which lie in the frwquency range 20 Hz to 20000 Hz are called audible or sound waves.
These waves are sesitive to human ear. These are generated by the vibrating bodies such as tuning fork, vocal cords etc.
(2) Infrasonic Waves : The longitudinal mechanical waves having frequencies less than 20 Hz are called Infrasonic.
These waves are produced by source of bigger size such as earth quakes, volcanic eruptions, ocean waves and by elephants and whales.
(3) Ultrasonic Waves : The longitudinal mechanical waves having frequencies greater than 20000 Hz are called ultrasonic waves.
Human ear can not detect these waves. But certain creatures like dog, cat, bat, mosquito can detect these waves. But not only detect but also produce ultrasonic.

Egyption Civilization
Egyption civilization : Egypt is called the 'Gift of the Nile'. Historians divided the history of Egypt into three periods; the Old Kingdom, the Middle Kingdom and the New Kingdom.
The Old Kingdom is also called the 'Age of the Pyramids'. The Egyption king was called the pharaoh. The Egyptions were the worshipper of the nature and sun was their most important god.

Pluto is not a Planet now
On the basis of the new definition of planet given by the IAU (International Astronomical Union), the world's top institution on space science research, leading astronomers participating in IAU's meet at Prague (Czech Republic) on August 24, 2006, declared that Pluto would no longer remain a planet.
Under the IAU's new guidlines, the number of planets in the Solar System has thus been reduced from nine to eight. Its merits mentioning here that, prior to this decision, Pluto had been holding the planetary status since its discovery in 1930 by Cyde Tombaugh.
Now, with the omission of Pluto from the Solar System, its membership has been restricted to the eight "classical" planets, namely Mercury, Venus, Earth, Mars, Jupitor, Saturn, Uranus and Neptune.
Weeks after it was demoted to a sub-planetary status, Pluto was given a new name to reflect its new status as a dwarf planet in September 2006. The former 9th planet was assigned the asteroid number 134340 by the Minor Planet Centre (MPC), the official organisation responsible for collecting data about asteroids and comets in our Solar System.

Centre of Gravity
Centre of Gravity : The centre of gravity of a body is that point through which the entire weight of body acts.
The centre of gravity of a body does not change with the change in orientation of body in space.
The weight of a body acts through centre of gravity in the downward direction.
Hence a body can be brought to equilibrium by applying a force equal to its weight in the vertically upward direction through centre of gravity.

Constitution
Constitution : Constitution is the foundational law of a country which ordains the fundamental principles on which the government or the governance of that country is based.
It lays down the framework and principal functions of various organs of the government as well as the modalities of interaction between the government and its citizens.
With the exception of the United Kingdom, almost all democratic countries posses a written constitution.

Our Galaxy : Milky Way Galaxy
Milky Way Galaxy was formed 5 billion years after the big bang. Latest known galaxy is the Dwarf Galaxy. Origin of the universe is explained by the Big Bang Theory, formulated and proposed by the Belgian astronomer and cosmologist Georges Lemaitre. Andromeda is our nearest galaxy.

Mesopotamians
Mesopotamian Civilization : In astronomy, the Mesopotamians made astonishing progress. They could calculate the length of the day and the night.
Mesopotamians divided the whole day into 24 hours. They divided the sky into 12 parts, each assigned a name. This has come down to us as the 12 signs of zodiac.
Another remarkable achievement of the Mesopotamians was the invention of a lunar calendar, based on the moon.

Economics
On PPP (Purchasing Power Parity) basis, India with a per capita GNI of $3768 continues to be in group of lower middle income economies, but with an acceleration in its growth rate of GDP to an average of 8% during 2000 and 2009, India is supposed to enter the group of upper middle income countries, very soon.
China has already entered the upper middle income group.
