Gaurav Seth 5 years, 1 month ago

If AOBC is a rectangle whose three vertices are A(0, 3), O(0, 0) and B(5, 0), then the length of its diagonal is

Solution:

Now, length of the diagonal AB = Distance between the points A(0, 3) and B(5, 0).

∴ Distance between the points (x,, y,) and (x , y ),

Hence, the required length of its diagonal is √34.

In an AC generator, the electrical current reverses direction periodically. In a DC generator, the electrical current flows only in one direction. In an AC generator, the coil through which the current flows is fixed while the magnet moves. The construction is simple and costs are less.

Explain important poloitical characteristics if mid 18 century of Europe

Gaurav Seth 5 years, 2 months ago

Five features of Eighteenth century in Europe were:

Eighteenth century in Europe was a period of intellectual, social and political transformations. This was the Age of Enlightenment. Intellectually and politically, the ideas of Locke, Hobbes and others gave rise of an idea of democracy that influenced people who later revolted against the monarchial form of governments. In sciences, universe and positions of planets came to be discussed.
Perhaps, one of the greatest developments in the eighteenth century Europe was the beginning of the feeling of nationalism. This could be seen in the French Revolution where people demanded the transfer of power from the monarchy to a body of French citizens.
With the beginning of the French revolution, the idea of liberty and equality also began to take shape which later affected every part of Europe.
In the economic sphere, the industrial revolution began in Britain in 1770’s. Later, it radically changed the human society, politics and environment.
Many countries of Asia began to be colonized and colonialism reached its height in the nineteenth century. In 1757, the Battle of Plassey was fought in India in which Britain occupied Bengal and within next 100 years was ruling almost the entire sub-continent.

Discribe the major changes in europe during the French revolution

Posted by Kaif Malik 5 years, 3 months ago

CBSE > Class 10 > Social Science

2 answers

Tejasvini S 5 years, 3 months ago

The French Revolution had a major impact on Europe and the New World. Historians widely regard the Revolution as one of the most important events in history.[1][2][3] In the short-term, France lost thousands of its countrymen in the form of émigrés, or emigrants who wished to escape political tensions and save their lives. A number of individuals settled in the neighboring countries (chiefly Great Britain, Germany, Austria, and Prussia), however quite a few also went to the United States. The displacement of these Frenchmen led to a spread of French culture, policies regulating immigration, and a safe haven for Royalists and other counterrevolutionaries to outlast the violence of the French Revolution. The long-term impact on France was profound, shaping politics, society, religion and ideas, and polarizing politics for more than a century. The closer other countries were, the greater and deeper was the French impact, bringing liberalism and the end of many feudal or traditional laws and practices.[4][5] However, there was also a conservative counter-reaction that defeated Napoleon, reinstalled the Bourbon kings, and in some ways reversed the new reforms.[6] Most of the new nations created by the France were abolished and returned to prewar owners in 1814. However, Frederick Artz emphasizes the benefits the Italians gained from the French Revolution: For nearly two decades the Italians had the excellent codes of law, a fair system of taxation, a better economic situation, and more religious and intellectual toleration than they had known for centuries.... Everywhere old physical, economic, and intellectual barriers had been thrown down and the Italians had begun to be aware of a common nationality.[6] Likewise in Switzerland the long-term impact of the French Revolution has been assessed by Martin: It proclaimed the equality of citizens before the law, equality of languages, freedom of thought and faith; it created a Swiss citizenship, basis of our modern nationality, and the separation of powers, of which the old regime had no conception; it suppressed internal tariffs and other economic restraints; it unified weights and measures, reformed civil and penal law, authorized mixed marriages (between Catholics and Protestants), suppressed torture and improved justice; it developed education and public works.[7] The greatest impact came in France itself. In addition to effects similar to those in Italy and Switzerland, France saw the introduction of the principle of legal equality, and the downgrading of the once powerful and rich Catholic Church to just a bureau controlled by the government. Power became centralized in Paris, with its strong bureaucracy and an army supplied by conscripting all young men. French politics were permanently polarized—'left' and 'right' were the new terms for the supporters and opponents of the principles of the Revolution.

Respiration is the process of taking in oxygen and giving out carbon dioxide. There are two types of respiration processes in humans:

External Respiration, that involves the inhalation and exhalation of gases.
Internal Respiration, that involves the exchange of gases between blood and body cells.

Respiration in humans takes place through the lungs. It is the largest organ of the human respiratory system. The air inhaled moves down the trachea into the lungs where oxygen is exchanged for carbon dioxide from the body tissues. Carbon dioxide is then exhaled out of the lungs through the mouth.
