Switzerland

A portion of present day Switzerland, along with part of the Kingdom of Burgundy, was added to the Salic Frank Empire of Conrad II, early in the century.

Western europe

Western Europe was the chief contributor to the 40% population increase in Europe in this an the first half of the next century. The Cluniac reforms raised the western monasteries beyond their previous level, so that they became oases of peace, learning and stability. (Ref. 113 )

Spain

Early in this century Jews of wealth and culture everywhere soared to positions of influence in Spain. Samuel ibn Bagrela, skillful Hebrew poet, superb Talmudist, master stylist in Arabic and astute military strategist and political administrator, rose to be vizierate of Granada in the Moslem area from 1030 to 1056. When the tables were turned and anti-Semitism returned, however, he was massacred. (Ref. 8 ) Thee were four main principalities in Spain, which can be described as follows:

Moslem Spain in the south As previously noted this had been an area of great prosperity and culture, but in this century civil wars between Arabs and Berbers became endemic, with the latter proclaiming independence in the south and west. They were joined soon by some of the eastern seaboard people so that only a shell of the Omayyad Caliphate remained in central Spain and even it collapsed about 1031. The great Al Hakim library (see page 487) was dispersed or destroyed. Several petty dynasties were founded on the ruins of the Omayyad Caliphate but after Alfonso VI of Castile took Seville, Ysuf-ibn-Tashfin, of a new Almoravid power in North Africa, was called to help and he did – inflicting great losses on the Christians at Zalacca in 1086. Ibn-Tashfin then returned to Africa because of pressing problems there, but he was called back again in 1090 an that time he made himself lord of Spain. As is apparent from the remarks above, part of the Moslems' troubles was the presence of so may diverse, often antagonistic factions, such as Yemenites, Syrians, Persians and Berbers. In spite of their difficulties and eventual withdrawal, the Moslems greatly influenced Spanish institutions, character and psychology, culture and language. (Ref. 137 , 15 , 196 )

Castile in the northwest Upon the death of Sanche the Great (originally from Navarre) Ferdinand I of Castile assumed the crown in 1035, conquered Leon in A.D. 1037 and then reconquered a good deal of Portugal from the Moors. Alfonso VI captured Seville and Toledo and installed in son-in-law as the Count of Portugal in 1093.

The iberian peninsula

It was the aggressiveness of Alfonso VI that precipitated the Moslems' call for help to the Almoravids in North Africa with their alleged 150,000 horse and 3,000 foot soldiers. A Castilian, Rodrigo (Ruy) Diaz, called "Cid" by the Moslems, initially was in the service of the Castilian kings, but after trouble with Alfonso VI he was exiled twice and finally went over to serve the Moslem king of Saragosa, which was an independent emirate in northwestern Spain

This transfer of allegiance was within his rights as a free lord in a feudal society (Ref. 213 )
. He eventually became the ruler of Valencia and remained as such until his death in 1099. Although cruel, selfish and proud, the legends about him resulted in his ultimate acceptance as a national hero. Among other accomplishments, he founded the world's first leprosarium. At that time in Spain a horse cost the equivalent of 50 oxen. French influence began to penetrate into the country through the Cluniac monks and Toledo eventually succeeded Cordoba as the center for translation and exchange of Mediterranean scripts and ideas. (Ref. 119 , 213 , 15 , 222 )

Questions & Answers

Three charges q_{1}=+3\mu C, q_{2}=+6\mu C and q_{3}=+8\mu C are located at (2,0)m (0,0)m and (0,3) coordinates respectively. Find the magnitude and direction acted upon q_{2} by the two other charges.Draw the correct graphical illustration of the problem above showing the direction of all forces.
Kate Reply
To solve this problem, we need to first find the net force acting on charge q_{2}. The magnitude of the force exerted by q_{1} on q_{2} is given by F=\frac{kq_{1}q_{2}}{r^{2}} where k is the Coulomb constant, q_{1} and q_{2} are the charges of the particles, and r is the distance between them.

what is a capacitor?
Raymond Reply
Capacitor is a separation of opposite charges using an insulator of very small dimension between them. Capacitor is used for allowing an AC (alternating current) to pass while a DC (direct current) is blocked.

which has a higher temperature, 1cup of boiling water or 1teapot of boiling water which can transfer more heat 1cup of boiling water or 1 teapot of boiling water explain your . answer
Ramon Reply
I believe temperature being an intensive property does not change for any amount of boiling water whereas heat being an extensive property changes with amount/size of the system.
Someone
Scratch that
Someone
temperature for any amount of water to boil at ntp is 100⁰C (it is a state function and and intensive property) and it depends both will give same amount of heat because the surface available for heat transfer is greater in case of the kettle as well as the heat stored in it but if you talk.....
Someone
about the amount of heat stored in the system then in that case since the mass of water in the kettle is greater so more energy is required to raise the temperature b/c more molecules of water are present in the kettle
Someone

Two bodies attract each other electrically. Do they both have to be charged? Answer the same question if the bodies repel one another.
JALLAH Reply
No. According to Isac Newtons law. this two bodies maybe you and the wall beside you. Attracting depends on the mass och each body and distance between them.

Are you really asking if two bodies have to be charged to be influenced by Coulombs Law?

What is specific heat capacity
Destiny Reply
Specific heat capacity is a measure of the amount of energy required to raise the temperature of a substance by one degree Celsius (or Kelvin). It is measured in Joules per kilogram per degree Celsius (J/kg°C).
