This chapter examines the Amerindian cultures of what will become colonial North America.
Once upon a time . . .
Once upon a time there were no human beings (Homosapien Sapien). Just animals and plants from little fluffy bunnies to behemoth mastodons. People were not indigenous to the Western Hemisphere, well, at least we have no evidence that people were indigenous to the Western Hemisphere. Rather, we believe that people migrated from Asia to what is today Alaska and Canada around 40,000 to 50,000 years ago. Our current archeological evidence (burned bones) suggests that people had settled into North America at least 35,000 years ago. The big lessons you need to understand in this chapter is that there existed some very old and established cultures long, long before the Europeans arrived because one outdated myth was that North America was an empty vessel and Europeans turned it into a venerable Garden of Eden. For the Europeans in general, and the English in particular, there was a right way of doing things and a wrong way of doing this. The right way was the European (English) way and the wrong way was the Indian way, and thus European colonists justified their taking over of Indian land and destroying Indian culture.
We believe that most Asian immigrants were hunters and gathers -they got their caloric intake through hunting animals and by collecting naturally-growing roots, tubers, and berries. Hunting and gathering is not the best way to ensure your caloric intake. First, hunting and gathering is very time and caloric intensive, second, relying on nature is sometimes problematic. What do you do in the winter? What if there is a drought? What if a pestilence destroys the wild-growing plants? Thus, we believe that shortly after arriving to North America, Amerindians (the descendants of the original waves of Asiatic immigrants) settled down and thus embraced agriculture. There are four interconnected results to the development of agriculture. First, life becomes more stable as people are less reliant on hunting and gathering for their caloric intake. Second, agriculture is a more reliable and diverse food source. Third, agriculture resulted in the growth of cities or towns -spaces were people collected themselves. And, in many of the Amerindian communities, archeologists have discovered walls surrounding the permanent buildings. Now, there are two reasons for walls: 1) to protect the people inside from the nasty stuff outside; or, 2) to keep people in; to keep them from leaving. Nevertheless, the growth of communities meant the creation of permanent structures, normally built near fresh water sources, and they built canals (for irrigation), dikes, and roads. These work projects tend to imply that there also existed some form of government. A body that makes decisions as to where to build the canals or where to put the roads. Unfortunately, Amerindians embraced an oral tradition of passing down history and thus you will not come across any diaries, papers, or documents that fully tell the story of Amerindian life.
Questions & Answers
A golfer on a fairway is 70 m away from the green, which sits below the level of the fairway by 20 m. If the golfer hits the ball at an angle of 40° with an initial speed of 20 m/s, how close to the green does she come?
A mouse of mass 200 g falls 100 m down a vertical mine shaft and lands at the bottom with a speed of 8.0 m/s. During its fall, how much work is done on the mouse by air resistance
Can you compute that for me. Ty

what is the dimension formula of energy?
Chemistry is a branch of science that deals with the study of matter,it composition,it structure and the changes it undergoes
Adjei
please, I'm a physics student and I need help in physics

chemistry could also be understood like the sexual attraction/repulsion of the male and female elements. the reaction varies depending on the energy differences of each given gender. + masculine -female.

A ball is thrown straight up.it passes a 2.0m high window 7.50 m off the ground on it path up and takes 1.30 s to go past the window.what was the ball initial velocity
2. A sled plus passenger with total mass 50 kg is pulled 20 m across the snow (0.20) at constant velocity by a force directed 25° above the horizontal. Calculate (a) the work of the applied force, (b) the work of friction, and (c) the total work.
you have been hired as an espert witness in a court case involving an automobile accident. the accident involved car A of mass 1500kg which crashed into stationary car B of mass 1100kg. the driver of car A applied his brakes 15 m before he skidded and crashed into car B. after the collision, car A s
can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing

what are the types of wave
Maurice
fine, how about you?

A string is 3.00 m long with a mass of 5.00 g. The string is held taut with a tension of 500.00 N applied to the string. A pulse is sent down the string. How long does it take the pulse to travel the 3.00 m of the string?
Who can show me the full solution in this problem?
