Victor Emmanuel II (1820-1878) was king of Sardinia from 1849 to 1861 and then the first king of Italy until 1878. He worked to free Italy from foreign control and became a central figure of the movement for Italian unification.

The son of Charles Albert, Prince of Savoy-Carignano, Victor Emmanuel was born at Turin on March 14, 1820. His education was not thorough or varied, its content being restricted largely to military and religious training. In his youth he took little interest in affairs of state, preferring to spend his time in the study of military strategy and tactics. In 1842 he married Adelaide, the daughter of Archduke Rainer of Austria.

Liber

Liberalism : Derived from Latin word Liber means free. It meant differently to different people. In political sphere, Liberalism means rule governed by elected parliament. Economically, liberalism means freedom of markets and removal of barriers that obstructe the free flow of trade.For woman, Liberalism indicated universal suffrage.They demanded that the voting rights should be extended to them.

Liberalism: Derived from Latin word ‘liber’ means ‘free’. It meant differently to different people.

Projectile Motion

When any object is thrown from horizontal at an angle θ except 90°, then the path followed by it is called trajectory, the object is called projectile and its motion is called projectile motion.

If any object is thrown with velocity u, making an angle θ, from horizontal, then

• Horizontal component of initial velocity = u cos θ.
• Vertical component of initial velocity = u sin θ.
• Horizontal component of velocity (u cos θ) remains same during the whole journey as no acceleration is acting horizontally.
• Vertical component of velocity (u sin θ) decreases gradually and becomes zero at highest point of the path.
• At highest point, the velocity of the body is u cos θ in horizontal direction and the angle between the velocity and acceleration is 90°.

Important Points & Formulae of Projectile Motion

1. At highest point, the linear momentum is mu cos θ and the kinetic energy is (1/2)m(u cos θ)².
2. The horizontal displacement of the projectile after t seconds
   x = (u cos θ)t
3. The vertical displacement of the projectile after t seconds
   y = (u sin θ) t — (1/2)gt²
4. Equation of the path of projectile
   
5. The path of a projectile is parabolic.
6. Kinetic energy at lowest point = (1/2) mu²
7. Linear momentum at lowest point = mu
8. Acceleration of projectile is constant throughout the motion and it acts vertically downwards being equal to g.
9. Angular momentum of projectile = mu cos θ x h, where h denotes the height.
10. In case of angular projection, the angle between velocity and acceleration varies from 0° < θ < 180°.
11. The maximum height occurs when the projectile covers a horizontal distance equal to half of the horizontal range, i.e., R/2.
12. When the maximum range of projectile is R, then its maximum height is R/4.

Numerical Coefficient

A numerical coefficient is a constant multiplier of the variables in a term.

• In the term -5x²y, the numerical coefficient is -5.
• In the expression ax² + bx + c, the numerical coefficient of the x² term is "a" and the numerical coefficient of the x term is "b". "c" is properly referred to as the constant term.

In direct current, the current flows in one direction only. Some sources of direct current are cell, DC generator, etc. Dry cell, dry cell battery, car battery and DC generator, radio and television works only with D.C they have a device in them which convert A.C supplied to them into D.C. The DC current is the current which does not change the direction with time.

Macromolecules are basically polymers, long chains of molecular sub-units called monomers. Carbohydrates, proteins and nucleic acids are found as long polymers. Due to their polymeric nature and large size, they are known as macromolecules.

The large complex molecules having molecular weights more than one thousand Dalton which occur in colloidal state in the intercellular fluid are called macromolecules. They are formed by the polymerization of low molecular weight micromolecules. For example: Polysaccharides, proteins, lipids, etc.

Subsistence Farming: When farming is done to meet the needs of the farmer’s family, it is called subsistence farming. In subsistence farming, low levels of technology and household labour are generally utilised. Farming is done on smaller plots and output is also small. Subsistence farming can be further categorized as intensive subsistence and primitive subsistence farming.

Intensive Subsistence Farming: In this type of farming, the farmer cultivates on a small plot of land. He uses simple tools and more labour. Places which have fertile soils and where the climate allows a large number of days with sunshine are suitable for this type of farming. In favourable climates, farmers are able to grow more than one crop in a year. Rice is the main crop in this type of farming. However, wheat, maize, pulses and oilseeds are also grown. This type of farming is prevalent in densely populated areas of the monsoon regions of south, southeast and east Asia.

iOS

iOS is used on the iPad, iPhone, iPod Touch, iPod Nano, and Apple TV. There is an on going trend to merge iOS with Mac OS X. In the Apple store over a million Apps are available for the iPhone, and over five hundred thousand Apps are optimized for the iPad.

Agricultural Development refers to efforts made to increase farm production in order to meet the growing demand of increasing population. This can be achieved in many ways such as: Increasing the cropped area. Multiple cropping (Number of crops grown in a year) Improving irrigation facilities.

(1) Maize:
• Requires moderate temperature, rainfall and lots of sunshine and also, needs well-drained fertile soils.

(2) Cotton:
• Cotton is a fiber crop grown in tropical areas. Cotton requires high temperature, light rainfall, 210 frost-free days and bright sunshine for its growth.
• It grows best on black soil and requires at least 6 to 8 months.

Tea:
• Tea is a beverage crop.
• Tea plants grow well in tropical and sub-tropical climate. It requires warm and moist free climate and well distributed frequent showers throughout the year. It needs deep, fertile, well-drained loamy soils and gentle slopes, rich in humus and organic matter.
• Cheap and skilled labour is required in large number to pick the leaves. Tea is processed within the tea gardens to restore its freshness.
• India, Kenya, China, Sri Lanka produce the best quality tea in the world.
• India is the leading producer and exporter of tea. Assam, Darjeeling, West Bengal and Tripura are leading producers of tea in India.

Coffee:
• Hill slopes are more suitable for growth of this crop.
• It requires warm & wet climate and well drained loamy soil.
• Brazil is the leading producer followed by Columbia and India.
• In India coffee is cultivated in Karnataka, Kerala and Tamil Nadu.

(a) Rice:
• Rice is the major food crop of the world. It is the staple diet of the tropical and sub-tropical regions.
• Rice needs high temperature, high humidity and rainfall. It grows best in alluvial clayey soil, which can retain water.

(b) Wheat:
• It requires moderate temperature and rainfall during growing season and bright sunshine at the time of harvest.
• It requires well drained loamy soil for its growth.

Isotopes: Isotopes are atoms with the same number of protons but that have a different number of neutrons. Since the atomic number is equal to the number of protons and the atomic mass is the sum of protons and neutrons, isotopes are elements with the same atomic number but different mass numbers.

Isobars: Atoms of different elements with different atomic numbers, which have the same mass number, are known as isobars.

A word processor, or word processing program, does exactly what the name implies. It processes words. It also processes paragraphs, pages, and entire papers. Some examples of word processing programs include Microsoft Word, WordPerfect (Windows only), AppleWorks (Mac only),

Walt Whitman

"The Voice of the Rain" is a short free-verse poem by the American poet Walt Whitman. Originally published in a periodical called Outing in 1885, it was later reprinted in Leaves of Grass, Whitman's most celebrated collection of verse.

• The wealthy middle class  replaced the jacobin government
• After the fall of the Jacobin government, the wealthy middle class seized power. A new constitution was introduced which provided for two elected legislative councils.
• These then appointed a Directory, an executive made up of five members. This was meant as a safeguard against the concentration of power in a one-man executive as was under the Jacobins.
