Create a Python program that will produce the following output:
Aloiza [94]

Answer:

def main ():

   sentence = input("Please enter a sentence:")

   print("Original Sentence:",sentence)

   # start at the third character

   for i in range(2,  len(sentence), 3):

       # access the string by index  

       print("Every third letter:", sentence[i])

Explanation:

def helps define the sentence ( input)

in order to start printing from third letter we start the range from 2 and keep the step 3 . The range i is in square parenthesis to show the range and access string.

The air standard efficiency ofan Otto cycle compared to diesel cycle for thie given compression ratio is: (a) same (b) less (c)
Svetach [21]

Answer:

Correct sentence: (c) more.

Explanation:

Otto cycle:

An ideal Otto cycle models the behavior of an explosion engine. This cycle consists of six steps, as indicated in the figure. Prove that the performance of this cycle is given by the expression

η = 1 - (1/r^(ρ-1))

where r = VA / VB is the compression ratio equal to the ratio between the volume at the beginning of the compression cycle and at the end of it. ρ=1.4

Diesel cycle:

The ideal Diesel cycle is distinguished from the ideal Otto in the combustion phase, which in the Otto cycle is assumed at a constant volume and in the Diesel at constant pressure. Therefore the performance is different.

If we write the performance of a Diesel cycle in the form

:

η = 1 - (1/r^(ρ-1)) × ( (r^ρ)-1)/(ρ^(r-1)) )

we see that the efficiency of a Diesel cycle differs from that of an Otto cycle by the factor in parentheses. This factor is always greater than the unit, therefore, for the same compression reasons r

                   diesel performance is less than otto performance

\ eta_ \ mathrm {Diesel} <\ eta_ \ mathrm {Otto} \,

Shelly cashman word 2016 module 2 - project a pdf - does anyone have the fished paper
JulijaS [17]

Answer:

GETTING STARTED

Open the file SC_WD16_2a_FirstLastNamedocx, available for download from the SAM website.

Save the file as SC_WD16_2a_FirstLastNamedocx by changing the “1” to a “2”.

If you do not see the .docx file extension in the Save As dialog box, do not type it. The program will add the file extension for you automatically.

With the file SC_WD16_2a_FirstLastNamedocx still open, ensure that your first and last name is displayed in the footer.

If the footer does not display your name, delete the file and download a new copy from the SAM website.

PROJECT STEPS

For your Written Communication class, you are writing a short research paper. To conform to MLA guidelines, modify the document’s Normal style by changing the font to Times New Roman, the font size to 12 pt., and the line spacing to double with no blank space after paragraphs.

Apply the modified Normal style to the first four paragraphs in the document, from “Crystal Mathison” to “15 October 2018”.

Center the title paragraph “A Solution to Food Deserts: Micro Farms”.

Insert a header as follows:

Insert a blank header at the top of the page.

Right-align the header paragraph.

Type Mathison as the header text, insert a space, and then insert a Plain Number page number from the Current Position gallery.

Close Header & Footer Tools.

Create a First Line indent of 5″ for the body paragraphs beginning with “In the United States…” and ending with “…avenues for profitable enterprises.”

the Citations & Bibliography Style of the document to MLA.

In the sentence “In the United States…fresh fruits and vegetables.”, move the insertion point before the period and insert a citation to a new source using the information shown in Figure 1 below. (Hint: The Tag name is intentionally blurred because it is generated automatically.)

Insert a citation to the existing Johnson source before the period in the third sentence, “Most food deserts are in cities such as…Oklahoma City.”

In the fourth sentence of the first body paragraph, “However, living in…fresh food options.”, use the Thesaurus to replace the word “assure” with a more common synonym that starts with the letter “g”.

In the second paragraph, find the sentence “The aim is…growth.” Move the insertion point before the period and insert a citation to a new source using the information shown in Figure 2 on the next page. (Hint: The Tag name is intentionally blurred because it is generated automatically.)

Figure 2: Article in a Periodical Source

To provide additional information at the end of the second paragraph, move the insertion point immediately after the period in the sentence “…fruit trees and bushes.” and insert a footnote with the following text:

Such practices are called companion planting.

Modify the Footnote Text style by changing its font size to 12 pt. and the line spacing to double.

In the main body of the document, find all instances of the text “abandoned” and replace it with vacant. (Hint: You should find and replace two instances.)

Cut the paragraph “Micro farms include private gardens…goods for sale and profit.” and then paste it so it becomes the third body paragraph in the document.

In the fifth body paragraph (“In rural locations…and two employees”), edit the Fortier citation to add the page number 25.

Modify the “Works Cited” paragraph as follows:

With the insertion point immediately before the “Works Cited” paragraph, insert a manual page break.

Center the “Works Cited” paragraph on the new page 3.

With the insertion point in the left-aligned blank paragraph at the end of the document, use the Insert Bibliography command to insert a list of sources without a built-in heading.

After reviewing the bibliography, you notice the year is missing from the Harris source. Find the Harris source and edit it, entering 2017 as the Year.

Update the bibliography field so the Works Cited list reflects the edit you made to the Harris source.

Check the Spelling & Grammar in the document to identify and correct any spelling errors. (Hint: Ignore names. You should find and correct at least one spelling error.)

Your document should look like the Final Figure on the following pages. Save your changes, close the document, and then exit Word. Follow the directions on the SAM website to submit your completed project.

Water is the working fluid in an ideal Rankine cycle. Superheatedvapor enters the turbine at 10MPa, 480°C, and the condenser pre
choli [55]

Answer:

Explanation:

Given that:

Superheated vapor enters the turbine at 10 MPa, 480°C,

From the tables of superheated steam tables; the following values are obtained

h_1 = 3322.02 \ kJ/kg\\\\ s_1 = 6.52846 \ kJ/kg.K

Also; from the system, the isentropic line is 1-2 in which s_2 is in wet state

s_2 = s_{f \ 6 kpa} +xs_{fg \ 6 kpa}

s_2 =0.51624 + x(7.82)

s_2 =0.51624 + 7.82x

From the values obtained;

s_1 =s_2= 6.52846 \ kJ/kg.K

Therefore;

6.52846 = 0.51624+7.82x

6.52846 - 0.51624 = 7.82 x

6.01222  = 7.82 x

x = 6.01222/7.82

x = 0.7688

The enthalpy for this process at state (s_2) can be determined as follows:

h_2 = h _f +xh_{fg} \\ \\ h_2 = 150.15 +(0.77 \times 2415.92) \\ \\ h_2 =150.15 +( 1629.2584 )  \\ \\ h_2 =2010.4084   \ kJ/kg

The actual enthalpy at s_2 by using the isentropic efficiency of the turbine can determined by using the expression:

n_T = \dfrac{h_1-h_{2a}}{h_1-h_2}

0.8 = \dfrac{3322.02-h_{2a}}{3322.02-2010.4084}

0.8 = \dfrac{3322.02-h_{2a}}{1311.6116}

0.8 * {1311.6116}= {3322.02-h_{2a}

1049.28928=  {3322.02-h_{2a}

h_{2a}=   {3322.02- 1049.28928

h_{2a}=   2272.73072 kJ/kg

The work pump is calculated by applying the formula:

w_p = v_{f  \  6 kpa} (p_4-p_3)

w_p = 0.0010062 * (10000-6)

w_p = 0.0010062 *9994

w_p = 10.0559628 \  kJ/kg

However;

w_p = h_4 -h_3

From the process;

h_3 = h_{f(6 kpa)} = 150.15 \  kJ/kg

10.0559628 = h_4 - 150.15

10.0559628+  150.15 = h_4

160.2059628= h_4

h_4= 160.2059628 \  kJ/kg

The actual enthalpy at s_4 by using the isentropic efficiency of the turbine can determined by using the expression:

n_P = \dfrac{h_4-h_{3}}{h_{4a}-h_3}
