What factors affect frictional force between objects?
Asked in Thomas Edison, Nikola Tesla
How long did Nikola Tesla work when Thomas Edison?
Long enough to see what kind of person he was. -0- "If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found the object of his search. I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor." -Nikola Tesla-

How do you calculate the explicit formula and the nth term of the Fibonacci sequence?
(1/sq rt 5)((1+sq rt 5)/2)n - (1/sq rt 5)((1-sq rt 5)/2)n This is based on the golden ratio (1+sq rt 5)/2) because the ratio of 2 Fibonacci terms approaches the golden ratio as the 2 terms used get larger. IE the ratio ot the 10th term to the 9th term is 55/34 = 1.61765 and the golden ratio is approx. 1.61803. When using this formula if your calculator does not round, you will round to get the appropriate Fibonacci number.
Asked in Reproductive System
What concentration of oxygen should be used with a full term newborn?
There are two main concerns when using oxygen on new born babies. One is oxygen toxicity, the other is meeting the babies oxygen requirements. On one hand, oxygen can actually be toxic, especially to pre-term babies from 32 weeks gestation and lower. High FiO2's(fraction of inspired oxygen) may even cause blindness (ROP), and Intracerebral bleeds (ICH). Secondly, the baby must have sufficient O2 to meets its bodies demands. I told you this so you know there is a difference in term newborn, and pre-term, oxygenation requirements. So, the simple answer to a complicated scenario is, apply the minimum FiO2 that will address the babies requirements. This is called oxygen titration.
What is the difference between how hurricanes and tornadoes form?
Asked in History, Politics & Society
Were the Cahuilla a violent tribe?
No. They were allied with both the Spanish and Anglo-Americans. Good relationships were maintained with the US Army, holders of Spanish Land Grants and neighboring Native Americans. History can fairly claim that the Cahullia were responsible for the deaths of 33 or more Luiseno prisoners in what is known as the Temecula Massacre during the Mexican American War. Perhaps Jose del Carmen Lugo should not have left his prisoners in the hands of their traditional enemies when the Spanish withdrew.

Asked in C Programming
Why is the importance of link section in programming c?
Compilation is a three-phase process: preprocessing, compilation and linking. The preprocessor's job is to prepare a source file (translation unit) for compilation. This is achieved by reading each source file, stripping out the user-comments, performing macro substitutions and acting upon any conditional compilation directives, writing the output to an intermediate file which contains only C code and nothing else. Thus there will be one intermediate file generated for each translation unit. The compiler's job is to create an object source file from an intermediate file. Object source files primarily consist of a machine code translation of the C source code followed by the symbol tables, which lists all the internal and external linkages of the translation unit. An external linkage is simply a type declaration which is not defined within the current translation unit; the definition may be provided by a type library or it may be provided by another translation unit. Either way, the compiler cannot generate the required machine code, so it uses a symbol (a placeholder) instead. Once all translation units are compiled to object files, the linker examines the linkage tables and uses that information to generate a single machine code executable from the object source, substituting the placeholders generated by the compiler and adjusting memory offsets to suit the resultant code.
Asked in Stamp Collecting (Philately)
Are cancelled stamps worth money?
Modern used stamps do have some value, but not much. Used stamps, still on paper are, typically sold in large lots by weight to collectors that are filling spaces in their albums. You can buy one pound lots for about $15 for a mostly commemorative lot. Older stamps, used or not, can be worth a great deal.
