Far north and canada

Back to America: 5000 to 3000 B.C.

There were always more people on the Aleutian Islands than on the mainland, because of a milder climate. Nevertheless, from 4,000 to 1,000 B.C. an Arctic Small Tool tradition existed in Alaska, spreading across the arctic part of Canada to Greenland, given its name from the miniature blades lashed to handles of bone or walrus ivory used for cutting and scraping skins. The blades were chipped from a core of chert, a rock of micro-crystalline quartz. These Asiatic people even migrated to Ellesmere Island in northeastern Canada, less than 800 miles from the North Pole, about 2,300 B.C., crossing over the mountains in a great notch, today known as Sverdrup Pass, to the upper end of Baffin Bay, which usually has open water at least in the summer. Canadian archeologists have excavated some of these pre-historic sites, where the earliest are now thirty to thirty-five meters above the present sea level, although they were originally on the beach. As in other northern areas of the globe, the earth's crust has risen slowly over the centuries after the lifting of the great weight of the glacial ice. From Ellesmere Island progress into northern Greenland over winter ice was no problem. By about 1,500 B.C. in British Columbia (and Washington state) people were settled in villages and fished for salmon, although they did not practice cultivation. (Ref. 209 , 45 , 189 )

This is the era of the so-called Red Paint Culture, with native Amerindian Stone Age traditions derived from old northeastern Asia. The Red Paint or Moorehead Culture originally described from prehistoric graveyards in Maine - the graves containing red ochre has now been identified as part of a larger maritime Archaic tradition extending from northern Labrador at the 60th parallel to southern Maine between about 2,000 and 1,500 B.C. This area was deglaciated about 7,000 B.C. with tundra then present until about 3,000 when spruce forests finally appeared. The settlement pattern and life styles of these Red Paint people seems to have been different from both the Eskimos and the Montagnais-Naskopi Indians of inland Labrador and Quebec. Hunting, fishing, trading tools and raw materials and burying their dead were definable activities. The roots of this culture may have extended back several thousand years to the Paleo-Indian hunters of the now submerged continental shelf. (Ref. 69 )

The united states

The reader is advised to review the preceding two paragraphs concerning Maine and Washington State. In the east the eastern Archaic Culture was changing about 2,000 B.C. in that there was the manufacture of some crude pottery and there was an increased attention to burial observances. Some call this the beginning of the Woodland Culture and others call it simply the Late Period of the Archaic of the Eastern Woodland. At the same time, in the southwestern states, specialized desert cultures continued to develop from the Archaic. As recorded in the last chapter, the Cochise began cultivating corn sometime from 3,000 to 2,000 B.C., providing them extra nourishment for their uncertain diet. Squash now was also brought up from Mexico and tiny gardens of both have been found all over the Cochise wandering area. Santa Catalina Island, twenty miles off the California coast, as previously noted, was inhabited and some forty Indian town sites have been identified. It is obvious that coastal Indians had facilities for ocean travel. (Ref. 45 , 64 , 210 , 187 )

Mexico, central america and the caribbean

The "Pre-Classic Age" of Middle America traditionally began about 2,000 B.C. with Mayan ancestors being simple village farmers, although the earliest Maya carbon dating on the Caribbean side of Yucatan goes back to between 2,750 and 2,450 B.C. It is entirely possible the Maya beginnings may go back to Ecuador at 3,000 B.C. while the Olmec civilization began separately on the Gulf coast much later. In 1977 Norman Hammond (Ref. 85 ) published results of archeological excavations in Belize (formerly British Honduras) which seem to confirm the origins of the Maya back at about 2,600-2,500 B.C. He describes a lowland pottery called "Swash", found in burial sites with human skeletons. The adults among the latter showed advanced tooth wear, suggesting abrasives in their diet. The Maya steeped corn in slaked lime before boiling, to soften it (and incidentally it released certain amino-acids not otherwise absorbable) and this lime, along with grit derived in the grinding process probably accounted for the tooth wear. These individuals also constructed raised earth platforms in swamps by digging out drainage channels and throwing the mud up to make platforms on which various crops were grown. The presence of jade, not naturally present within 350 kilometers, indicates a trade network. Their Swasey ceramics - colorful, decorative and mature - are different from that of Mexico and the southern United States of 2,500 B.C., but are similar to Ecuadorian pottery of this period. Throughout Central America maize-farming had become the basis of life by 1,500 B.C. and the farmers lived in permanent villages. By the same date in the Tehuacan Valley of Mexico, there was complex village life, pottery, elaborated religious rituals and intricate social organization. Corn and pottery have been dated to 2,000 B.C. in Panama. (Ref. 45 , 95 , 85 , 64 , 62 )

South america

Valdiva, as a coastal society in Ecuador, like Panama, had corn and pottery by about 2,000 B.C.

Thomas (Ref. 213 ) says the Ecuadorians had pottery even earlier, at 3,200 B.C.
. Evans and Meggers, of the Smithsonian Museum, are impressed with the similarities between Valdivian pottery and the Jomon pottery of Japan, believing Ecuador may have been the landing place of a Japanese immigration, thus bringing one more possibility of Asian diffusion to the Americas. We shall examine other ideas in other chapters. Potatoes were cultivated in the Andes by 3,000 B.C., manioc was grown on the tropical lowlands and there were domesticated animals in South America shortly after 2,000 B.C. Ceremonial centers found along the desert coast of Peru date to about the same time as did evidence of metal working. The Ancon Yacht site on the coast of Peru, dated 2,500 to 2,000 B.C. showed chipped leaf points, string, turned cloth and baskets, wooden tools, shell fishhooks and cultivated plants which included gourds, cotton and chili peppers.

The Peruvians used the potato by 3,000 and soon domesticated the guinea pig for food. Coastal Peruvians gathered protein-rich shell fish off the beaches by 2,800 and by 2,500 B.C., when the villages were large, far out ocean fishing for larger fish was common. (Ref. 62 , 45 , 209 , 211 , 222 )

Early farmers were probably well established on the Ecuadorian sea coast and river plains by 3,000 B.C. Contact with Mesoamerica was certainly possible by water, but otherwise there was a 2,000 mile jungle stretch between them. What Engel (Ref. 62 ) calls the "bean planters society" came into being in the lower central Andes, along with cotton clothes and underwear at about 2,000 B.C. The bones of sea-lions are mixed with those of these early agriculturalists. Excavations in Venezuela, like adjacent areas, show evidence of manioc and sweet potato cultivation from between 3,000 and 2,700 B.C. Both of these are root crops, but manioc required special preparation to be made palatable. (Ref. 95 , 62 , 209 )

Forward to America: 1500 to 1000 B.C.

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.

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?
