The far east

Back to The Far East: A.D. 901 to 1000

China and manchuria (sung dynasty)

The Northern Sung capital, Kaifeng, is said to have had over 50 theaters, some large enough for several thousand patrons, entertained by acrobats, dancers, clowns, musicians and actors. China, in this century, was the most populous, prosperous and cultured nation on earth. A new invasion in the northwest by Uigurs in A.D. 1035 and the rise of a Western Xia Dynasty (1032-1227) apparently did little damage to the main area of China, but they did cut off Dunhuany completely from the mainstream of Chinese culture.

(Ref. 282 )

After A.D. 1000 Neo-Confucianism, having absorbed important elements from Buddhism and Taoism, emerged unchallenged as the official intellectual system of China. This was a victory for the gentry as against the mercantile and military intruders, although industry continued to thrive. One of the greatest Sung advances was the introduction of the Champa rice, a new strain more drought resistant and faster ripening than previous varieties

In later centuries this was to be reduced to 30 days, through seed breeding. (Ref. 101 )
. Even then, however, the southern Chinese never attempted to conquer the mountain regions. With insufficient draft animals the wretched mountain-dwellers grew rice on dry land and did not participate in the low-lander peasant prosperity. (Ref. 260 )

Hundreds of workmen in the Kaifeng region were employed in large scale coal and iron complexes, accounting for about 1/2 of the country's total iron production. One huge complex at Ch'its'un in Hopei had 700 coal miners, 1,000 ore miners and 1,000 blast furnace workers, producing annually some 42,000 tons of coal and over 14,000 tons of pig iron. The national total iron production was 125,000 tons a year, by A.D. 1078. (Ref. 279 ) Although the principal of the blast furnaces had been known in China for 1,000 years, it was the use of coke in the early decades of this 11th century which solved not only the fuel shortage but greatly improved the iron and steel production. Canals connected the capital, Kaifeng, with Honan and Hopei and it became a vast market for the iron and steel. But the government continued to closely supervise the minting of coins (made from iron) and the manufacture of weapons and agricultural implements after 1083 with carefully controlled directives and taxation. A rising population meant that poverty did not disappear even in the face of the rising production, with the old story of "the rich got richer and the poor got poorer". (Ref. 279 ) It is one of the main hypotheses of the historian, William H. McNeill's recent book Pursuit of Power (Ref. 279 ) that China's rapid start toward industrialization and rapid change towards a market-regulated (as opposed to a "command" society) behavior in this and the next few centuries tipped a critical balance in world history. While politicians found it less and less possible to escape the effects of the financial market interchange, new forms of management and compromise between rulers, military power and money power had to be developed. (Ref. 101 )

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

how do lnternal energy measures

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.
Dlovan
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).
