Explain how liquids can be analyzed by gas chromatography.
Briefly define or describe the function, in gas chromatography,
of the
carrier gas:
stationary liquid phase:
solid support:
If ethyl acetate and n-butyl acetate are analyzed by gas
chromatography, which of these esters will generally produce a peak
with the shorter retention time?
What operating variables determine retention time?
Explain why is it important to inject the sample quickly.
How do economists define money? Explain. What are the three
functions of money? Explain each. Explain the evolution of money
from the 19th century to modern times. How can a rapid
inflation degrade the ability of money to carry out its three
functions? Explain.
Python 3 Forming Functions
Define and complete the functions described below.
* function name: say_hi
* parameters: none
* returns: N/A
* operation:
just say "hi" when called.
* expected output:
>>> say_hi()
hi
* function name: personal_hi
* parameters: name (string)
* returns: N/A
* operation:
Similar to say_hi, but you should include the name argument in the
greeting.
* expected output:
>>> personal_hi("Samantha")
Hi, Samantha
* function name: introduce
* parameters: name1 (string)
name2 (string)
* returns: N/A...
Python 3 Functions that give answers
Define and complete the functions described below.
* function name: get_name
* parameters: none
* returns: string
* operation:
Here, I just want you to return YOUR name.
* expected output:
JUST RETURNS THE NAME...TO VIEW IT YOU CAN PRINT IT AS
BELOW
>>> print(get_name())
John
* function name: get_full_name
* parameters: fname (string)
lname (string)
first_last (boolean)
* returns: string
* operation:
Return (again, NOT print) the full name based on the first...
Briefly explain how levelling is carried out and the formation
of the collimation error. How can the collimation error be
eliminated? Also, describe other possible sources of error in
levelling, and explain what precautions can be taken to avoid these
errors.
i. Define Fourier Series and explain it usefulness. At what
instance can a function ?(?) be developed as a Fourier
series.
ii. If ?(?)=12(?−?), find the Fourier series of period 2? in the
interval (0,2?)
What are the three main functions of money? Explain each
function using the example of how cigarettes performed each
function in the prisoner of war camp article. Which function is the
most important and why?
