Compare and contrast autarky and trade. How does trade help nations attain a higher production possibilities frontier? According to David Ricardo how does comparative advantage accomplish the aforementioned? Specify which groups gain and which lose.

Explanation:

Autarky is a policy against external trade;  a closed economy that does not allow external trade, in an attempt to reduce a country’s dependence on external trade.

Trade in itself could be internal or external. According to economist David Ricardo a country having comparative advantage implies that the economy has the ability to produce goods and services at a lower opportunity cost than that of trade partners.

The group that gains in the case of International trade may lose in the long-run if a country imposes high tariffs and stops international trade, it may produce a local benefit in the form of new jobs and industry. However, this country will lose relative to its neighbors: countries that were already better able to produce these items at a lower opportunity cost.

when the volume of gas is   changed from   717.73 ml   to 852 ml   the temperature will   change   from 315   c to 452   c

    calculation

this is calculated using the charles law formula

that is,   v1/t1 = v2/t2

          v1=?

        t1 = 315 c   into   kelvin = 315 +273 = 588 k

        v2 = 852   ml

        t2 = 425c + 273 =698 k

make v1   the subject of the formula ( by   multiplying both side by t1)

  v1=( v2 xt1) / t2

v1= (852 ml   x 588 k)/ 698 k= 717.73 ml
