Answer: The location of the Inca Civilization of South America demonstrates the ability of humans to adapt the environment.
Explanation:
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.

Gleick is thankful to Gutenberg for inventing the printing press.
Explanation:
Johannes Gutenberg (1398–1468), the inventor of typology through type. He was a resident of Mainz in Wejermani. He created the printing press in 1739, which is considered a great invention. He also created a movable type. The Bible printed by him is famous as Gutenberg Bible. Around 1439 AD, Strasbourg tested its printing invention.
Thus the first printed book is 'Constan Missal' which was published around 1450. Only three copies are available. One is in Munich (Germany) the other in Zurich (Switzerland) and the third in New York. In addition, a Bible was also printed by Gutenberg.
To manage the business in other nations, large corporations dispatch their workers there. Due to the affordable labour, IT giants and other MNCs outsource to Asia. In the United States, businesses ceased recruiting full-time employees following the recession of 2007–2008 and began using freelancers instead. The gig economy refers to this.
Part-time workers for an organisation are freelancers. The freelancers are employed by a company on a part-time basis, and after the project is complete, they are let go.
An organisation can request that its laid-off workers train their corresponding replacements. However, the employees who are being laid off are not required by law to do the same.
