Answer:
The viscous shear stress is 968 Pa (or can be written as 968 [tex]N/m^2[/tex]) and the drag force is 968 N.
Explanation:
Viscous shear stress
For a parallel flow of a Newtonian fluid, the shear stress is proportional to the gradient of the velocity,
[tex]\tau_{yx}= \mu \cfrac{du}{dy}[/tex]
Considering a large square plate moving on a thin film of thickness h, the velocity profile is
[tex]u(y) = U\cfrac{y}{h}[/tex]
Thus its derivative will be just
[tex]\cfrac{du}{dy}= \cfrac U h[/tex]
So replacing on the viscous shear stress formula we get
[tex]\tau_{yx}= \mu \cfrac {U}h[/tex]
We can then replace the given information
[tex]\tau_{yx}= 0.968 \times \cfrac{kg}{m\times s}\times \cfrac{0.1 \cfrac ms}{0.0001 \, m}[/tex]
Evaluating we get
[tex]\boxed{\tau_{yx}=968\, Pa}[/tex]
The viscous shear stress is 968 Pascals or [tex]N/m^2[/tex].
Drag force
Using the given equation for the drag force we have
[tex]D = \tau_{yx} A[/tex]
And since we have a large square plate of sides L we can write the area as
[tex]A = L^2[/tex]
So the drag force is
[tex]D = \tau_{yx} L^2[/tex]
Replacing values
[tex]D = 968\, Pa \times (1\, m)^2[/tex]
We get
[tex]\boxed{D= 968 \,N}[/tex]
The drag force is 968 N.
A student wants to restate some ideas she found in a journal article by a prominent expert in economics. She combines her own words with some of the expert's words, which she does not put in quotation marks. She references the article at the end her work. This is:
Explanation:
Althought she referenced the article at the end, is imposible to know which part of the article is hers and which part is the expert's so that would be plagiarism.
If she used quotation marks in the words of the expert it would be clear and no plagiarism could be accused.
The scenario describes plagiarism, which occurs when one uses someone else's work or ideas without proper citation. Even though the student referenced the source at the end, not using quotation marks for direct quotes is considered plagiarism.
Explanation:The scenario mentioned describes plagiarism. Plagiarism is a serious academic offense that occurs when one represents someone else's ideas, words, or work as their own without acknowledging the original source. In this case, the student has used the expert's words and ideas without proper citation (because she did not use quotation marks to indicate the direct quotes).
Although she mentioned the source at the end of her work, failing to use quotation marks for direct quotes is still considered plagiarism. To avoid this, it is essential to use quotation marks when directly quoting from a source and to paraphrase correctly when you are conveying the same idea in your own words.

Ninety-five percent of the acetone vapor in an 85 vol.% air stream is to be absorbed by countercurrent contact with pure water in a valve-tray column with an expected overall tray efficiency of 50 %. The column will operate essentially at 20 ºC and 101 kPa pressure. Equilibrium data for acetone-water at these conditions are: Mole percent acetone in water 3.30 7.20 11.7 17.1 Acetone partial pressure in air, torr 30.00 62.80 85.4 103.0 Calculate:
(a) The minimum value of S/G, the ratio of moles of water per mole of air.
(b) The number of equilibrium stages required using a value of S/G of 1.25 times the minimum. (please indicate operating line obviously)

Products that are in the process of being manufactured but are not yet complete are called:
Answer:
Those products are generally called Work in Process WIP
Explanation:
Work in process (WIP), or work in progress (WIP), goods in process, or in-process inventory in a manufacturing industry/company refer to the company's partially finished goods waiting for completion and eventual sale or the value of these items.
These items are either just being produced or require further processing (like purification, separation, packaging or handling) in a queue or a buffer storage.
Although Larry never went out for any sport at his high school, he could be seen in the stands of every game wearing the school’s colors and cheering wildly for his team. When they won, he felt exhilarated and would tell people, "We won! I knew we could do it," as if he had played the whole game himself. Larry is exhibiting which defense mechanism?
Larry is exhibiting the defense mechanism known as Identification
Identification is a defense mechanism where an individual unconsciously takes on the characteristics, feelings, or behaviors of another person or group that they admire or identify with. In this case, Larry, who did not participate in sports himself, identifies closely with his school's sports teams.
By wearing the school's colors, cheering for the team, and feeling exhilarated when they win, Larry is psychologically aligning himself with the team and deriving a sense of belonging and accomplishment from their success, as if it were his own. This behavior allows Larry to cope with any feelings of inadequacy or unfulfilled desires he may have regarding his own athletic abilities.
Create a program that calculates the monthly payments on a loan using Decimal & LC Console SEE Sanple Run Attached Specifications The interest rate should only use 1 decimal place for both the calculation and the formatted results. The formula for calculating the monthly payment is: monthly_payment = loan_amount * monthly_interest_rate / (1 - 1 / pow( (1 + monthly_interest_rate), months)) Assume that the user will enter valid data.
Answer:
Consider the following code.
Explanation:
Code:
Unix Terminal> cat loan_calc.py
#!/usr/local/bin/python3
import locale
from decimal import *
def main():
locale.setlocale(locale.LC_ALL, 'en_US')
print('Monthly Payment Calculator')
while True:
print('DATA ENTRY')
loan_amt = input('Loan amount: ')
loan_amt = float(loan_amt)
int_rate = input('Yearly interest rate: ')
int_rate = float(int_rate)
years = input('Years: ')
years = int(years)
mon_rate = int_rate / 12 / 100
months = years * 12
monthly_pay = loan_amt * mon_rate / ( 1 - 1/(1 + mon_rate) ** months)
monthly_pay = Decimal(monthly_pay).quantize(Decimal('.01'), rounding=ROUND_DOWN)
print()
print('FORMATTED RESULT')
print('Loan amount: %30s' %locale.currency(loan_amt))
print('Yearly interest rate: %20.2f' %int_rate + '%')
