It takes nd/ (lambda*f) time or a short pulse of light to travel from one end of the glass to the other.
If we talk about free space, that is, vacuum, light travels at a speed of 3x10^8 m/s, yet inside a glass light travels at a speed of v= c/n, where v is the velocity of the light and n is the refractive index. Now,
v=d/t,
so t= d/v
t= d/ (c/n)= n*d/c
c= lambda*f
t= nd/(lambda*f)
here, d is the thickness of the block, t is the time required and c refers to speed of light.

Truman Doctrine is a departure from previous American foreign policy in that it D. turned the United States away from its policy of isolationism. Prior to the doctrine, America had nothing with the wars outside that country. However, after the Doctrine was implemented, basically Cold War began.
Answer: Continental Congress
Explanation:
The Continental Congress adopted the Articles of Confederation, the first constitution of the United States, on November 15, 1777, but the states did not ratify them until March 1, 1781. The Articles created a loose confederation of sovereign states and a weak central government, leaving most of the power with the state governments. Once peace removed the rationale of wartime necessity the weaknesses of the 1777 Articles of Confederation became increasingly apparent. Divisions among the states and even local rebellions threatened to destroy the fruits of the Revolution. Nationalists, led by James Madison, George Washington, Alexander Hamilton, John Jay, and James Wilson, almost immediately began working toward strengthening the federal government. They turned a series of regional commercial conferences into a national constitutional convention at Philadelphia in 1787.
Answer:When I was, oh, <em>around</em> eight years old, I thought it would be fun to learn to play the piano. My parents agreed to purchase a piano. They told me that I would be required to practice one hour a day, <em>due to the fact that </em>piano lessons were expensive. At first, I practiced piano for two hours each day, <em>with the result that</em> I progressed very rapidly. Every day for two years I raced home <em>when </em>school was done and practiced the piano with great enthusiasm. Then one day, something happened. I decided I liked baseball better than the piano. Though I can play the piano rather well <em>at the present time</em>, I do not practice as long nor as diligently as I once did.
