Air has 1.00 n, so basically you can do n1s1 = s2 and plug into there.

I'm also good at Philosophy, but I give that class in Spanish and my school...having to translate what I know would make it kinda sloppy, but I can still help. I might need help with Calculus. >.>;;

Crit McGee on Speed Posts: 2,836 Group: Veteran Member #436 Joined: October 1, 2005	I need some help for an online class. Can anyone point me in the direction of some articles that deal with microeconomics? I need to write a summary of that article, and its supposed to be within the past few months. Any ideas of what to google search would be good too, because I can't find any more recent ones.

Crit McGee on Speed Posts: 2,836 Group: Veteran Member #436 Joined: October 1, 2005	From www.ushistory.org: Non-importation Agreements Colonial resistance to British control took many forms, perhaps the most effective was the general success of the non-importation agreements. Such agreements appeared as early as 1766. They had a chilling effect on the British Merchants who traded with the colonies. The Stamp Act was repealed, eventually, based on appeals from Merchants who lost money shipping goods to a land that would not receive them. Not incidentally, the customs offices in the colonies could not collect taxes on goods that were either not allowed ashore at all, or were never sold. Non-importation agreements reached ultimate effect in response to the Townshend Revenue Act, when in 1768 Boston passed the act seen below. Every port city and nearly every region would soon adopt acts like this one. Finally, in 1774, the first Continental Congress of the colonies would pass The Association, a colony-wide prohibition against any trade with Great Britain. Im assuming that they were the agreements between colonists to ban british goods, and only trade with each other if possible instead, which led to the forming of the association.
