Answer:
The following command is issued
in Windows command prompt
followed by the HTTP GET
message to the “utopia.poly.edu"
web server:
> telnet utopia.poly.edu 80
As the index.html page in the web
server was not modified since
Mon, 18 May 2015 09:23:34GMT,
the following outputwas displayed
when the above commands were
issued on Sat, 23 May 2015.
The first 4 lines are the GET
message and header lines input by
the user.
The next 4 lines (starting from
HTTP/1.1 304 Not Modified) are
the response from the web server.
Explanation:
File is also attach which might help to explain the answer.
Answer:
Na = 5.911 × atoms/cm³
Explanation:
given data
silver-gold alloy C Au = 17 wt%
densities ρ Au = 19.32 g/cm³
densities ρ Ag = 10.49 g/cm³
atomic weights A Au = 196.97 g/mol
atomic weights A Ag = 107.87 g/mol
solution
we will apply here formula for number of gold atoms that is
Na = ............................1
here NA is Avogadro's number and ρ is density of two element and A is atomic weight
put here value
Na =
Na = 5.911 × atoms/cm³
