question:
Force is a vector. What then is a vector? Think about how you would give directions to a friend. You would not say, just walk half a mile. The person may walk a half mile in the wrong direction! More information is needed. You may say, follow this particular road for a half mile. You may say, look for the green house on Sumter St. In both examples, you provided a direction. You also gave the distance. In other words, you provided a vector. You did not just give a distance. Both pieces of information are needed to find a location. This is just like describing forces. To explain forces, both size and direction are needed. Notice the girl in Figure 1.1. She is pushing the swing away from herself. Thats the direction of the force. She can give the swing a strong push or a weak push. <sep>If you know a force magnitude already, then what else do you need in order to give you the knowledge of a vector?<sep>Direction
answer:
Yes

question:
The earliest signs of people on Jamaica are the remains of the Arawak, an AmerIndian society that originated on the north coast of South America. Arawak peoples migrated to various Caribbean islands, arriving in Jamaica by the beginning of the eighth century. They were peaceful and lived by "slash-and-burn" farming. For meat, they bred pigs and ate iguana, both native to the island. They were highly skilled in such manual activities as thatching and weaving. In fact, the hammock was an AmerIndian invention that remains with us today; it is an object which, more than any other, evokes an image of a warm sunny day on a tropical isle. The Arawak left a legacy of paintings in places such as Runaway Caves near Discovery Bay, and shards of pottery found at their settlements near Nueva Sevilla and Spanish Town have added a little to our knowledge about them. Over 200 Arawak sites have been identified, and it is said that when the Spanish arrived in Jamaica there were approximately 100,000 Arawak living on the island. They called Jamaica "Xaymaca" ("land of wood and water"). Columbus and the Arrival of Europeans Columbus first arrived in Jamaica on 5 May 1494 at Discovery Bay, where there is now a small park in his honor. He stayed for only a few days but returned in 1502, landing here when the ships of his fleet became unserviceable; he waited at St. Ann's Bay for help to arrive from Cuba. After the death of Columbus in 1505, Jamaica became the property of his son Diego, who dispatched Don Juan de Esquivel to the island as Governor. Esquivel arrived in 1510 and created a base called Nueva Sevilla near St. Ann's Bay, from which he hoped to colonize the rest of the island. The Spanish immediately began subjugating the Arawak population, many of whom died under the yoke of oppression and of diseases carried by the Europeans. A number of them committed suicide rather than live the life created for them by the Spanish. The site of Nueva Sevilla proved to be unhealthy and mosquito-ridden, and in 1534 the Spanish founded Villa de la Vega, today known as Spanish Town. Pig breeding was the main occupation of these early settlers, but they also planted sugar cane and other crops that required large numbers of laborers. The number of Arawak had already fallen dramatically, so the Spanish began to import slaves from Africa to work the land; the first Africans arrived in 1517. <sep>For approximately how many years were the Arawak on Jamaica before the arrival of the Europeans?<sep>About 6 centuries
answer:
No

question:
We drove about a great deal--the country at the back of Deauville, going away from the sea, is lovely--very like England--charming narrow roads with high banks and hedges on each side--big trees with spreading branches meeting overhead--stretches of green fields with cows grazing placidly and horses and colts gambolling about. It is a great grazing and breeding country. There are many haras (breeding stables) in the neighbourhood, and the big Norman posters are much in demand. I have friends who never take their horses to the country. They hire for the season a pair of strong Norman horses that go all day up and down hill at the same regular pace and who get over a vast amount of country. We stopped once or twice when we were a large party, two or three carriages, and had tea at one of the numerous farmhouses that were scattered about. Boiling water was a difficulty--milk, cider, good bread and butter, cheese we could always find--sometimes a galette, but a kettle and boiling water were entirely out of their habits. They used to boil the water in a large black pot, and take it out with a big spoon. However, it amused us, and the water really did boil. <sep>When the author stopped for tea, was finding milk difficult?<sep>Yes
answer:
No
