Please help with the questions

1. The oil is mostly used for transportation, the coal for electric power, and around 13% are for export.

Explanation:

The United States are the biggest economy in the world. It is also a country that is abundant in pretty much all of the most demanded and needed resources, including the oil and the coal. Both of these resources fall into the category of nonrenewable ones, and their primary use is to get energy.

The oil and the coal are used in lot of different sectors. The oil is mostly used in the transportation, be it transportation of people or goods. The coal, on the other hand, is mostly used for production of electric power at the power plants. Not much of the coal is exported though, as the United States are huge consumers of it, so only about 13% of it is exported to other countries.

2. Between year 1 and year 11 the population sharply increases, between year 11 and year 9 it largely stagnates, between year 11 and 19 intracompetition has occurred, and after year 25 the population will drop down to a certain degree because of increased predation.

Explanation:

The pheasant population is on an island where it doesn't really have predators and there are more resources than what the initial population uses. This has caused exponential rise of the population between the years 1 and 11. Between year 9 and year 11 though, it is noticeable that the rise has pretty much stopped and the reason for that is that the population has reached its limit because of the limited resources, so an intracompetition occurs that stops the rise.

Over the coming years the population is largely stagnating in its numbers, but that will change after year 25. The reason behind that is that the family of coyote that moved in prey on the pheasants, so with such abundance of pheasants the number of coyote will skyrocket, while the number of pheasants will decrease.

acceleration= v2-v1/t so 8m/s-3m/s / 3s =to 8/3 or

2.67 m/s^2
