Three Use-Case Narrative. Choose one major use-case for each player (Customer, Shop Owner, and Administrator).

Answers

Answer 1
Numa máquina térmica uma parte da energia térmica fornecida ao sistema(Q1) é transformada em trabalho mecânico (τ) e o restante (Q2) é dissipado, perdido para o ambiente.



sendo:

τ: trabalho realizado (J) [Joule]
Q1: energia fornecida (J)
Q2: energia dissipada (J)


temos: τ = Q1 - Q2

O rendimento (η) é a razão do trabalho realizado pela energia fornecida:

η= τ/Q1

Exercícior resolvido:
Uma máquina térmica cíclica recebe 5000 J de calor de uma fonte quente e realiza trabalho de 3500 J. Calcule o rendimento dessa máquina térmica.

solução:

τ=3500 J
Q1=5000J

η= τ/Q1
η= 3500/5000
η= 0,7 ou seja 70%

Energia dissipada será:



τ = Q1 - Q2
Q2 = Q1- τ

Q2=5000-3500
Q2= 1500 J

Exercicio: Qual seria o rendimento se a máquina do exercicio anterior realizasse 4000J de trabalho com a mesma quantidade de calor fornecida ? Quanta energia seria dissipada agora?

Write a program that grades arithmetic quizzes as follows: Ask the user how many questions are in the quiz. Ask the user to enter the key (that is, the correct answers). There should be one answer for each question in the quiz, and each answer should be an integer. They can be entered on a single line, e.g., 34 7 13 100 81 3 9 10 321 12 might be the key for a 10-question quiz. You will need to store the key in an array. Ask the user to enter the answers for the quiz to be graded. As for the key, these can be entered on a single line. Again there needs to be one for each question. Note that these answers do not need to be stored; each answer can simply be compared to the key as it is entered. When the user has entered all of the answers to be graded, print the number correct and the percent correct.

Answers

Answer:

The program in C++ is as follows:

#include <iostream>

using namespace std;

int main(){

   int questions, answer;

   cout<<"Questions: ";

   cin>>questions;

   int answerkey[questions];

   cout<<"Enter answer keys: ";

   for(int i = 0; i< questions; i++){

       cin>>answerkey[i];    }

   int correct = 0;

   cout<<"Enter answers: ";

   for(int i = 0; i< questions; i++){

       cin>>answer;

       if(answer == answerkey[i]){

           correct++;        }    }

   cout<<"Correct answers: "<<correct<<endl;

   cout<<"Percentage correct : "<<(100 * correct)/questions<<"%";

   return 0;

}

Explanation:

This declares the number of questions and the answers submitted to each equation

   int questions, answer;

Prompt to get the number of questions

   cout<<"Questions: ";

This gets input for the number of questions

   cin>>questions;

This declares the answerkey as an array

   int answerkey[questions];

Prompt to get the answer key

   cout<<"Enter answer keys: ";

This iteration gets the answer key for each question

   for(int i = 0; i< questions; i++){

       cin>>answerkey[i];    }

This initializes the number of correct answers to 0

   int correct = 0;

Prompt to get the enter the answers

   cout<<"Enter answers: ";

This iterates through the answer keys

   for(int i = 0; i< questions; i++){

This gets the answer to each question

       cin>>answer;

This compares the answer to the answer key of the question

       if(answer == answerkey[i]){

If they are the same, correct is incremented by 1

           correct++;        }    }

Print the number of correct answers

   cout<<"Correct answers: "<<correct<<endl;

Print the percentage of correct answers

   cout<<"Percentage correct : "<<(100 * correct)/questions<<"%";

Explanation:

They are already talking business to business collects in which we are calling the client for collecting whenever the products which we have purchased are overdue and overdue inside 30 days. About business criteria, we should ensure no other websites mostly on agent acting open up so that nobody can misuse it; we also have to know the correct revising and trying to run off all systems and therefore all apps are organ systems because then the critical business work time has would not get out of the way. This is about the security of information. The agents also are adequately taught in IT policy according to the demand of the company.

They soon come towards the area of risk, experience, and skill. All agents ought to have proper refresh sessions to fulfill GAP knowledge but also improve their abilities for 100 percent cent accuracy on TAT on every appeal. Your Agency's response.

There ought to be a right party connect. We must keep up with 80-20 RULE which means that we can easily acquire the bigger amount earlier than somehow investing whatever money for future production if we concentrate on TOP 20 Overdue Current Passengers.

When we add up the current sum owing as well as the amount due by both the end of the month, so we will subtract all promises that were made by the end of each month. You can readily deduce how long and how much money will be received by the end of each month, and how long this will be due by the end of each month.

The total danger which we imagine to be cash flow issues is when a company is close to collapse or even has a money problem, they are few risks that any company has.

To solve this RISK to money flow clients, we have to provide them a payment plan so that we could at the very least invest some cash in additional production. Besides offering customers a pay system, you truly cannot help.

Another key potential risk is the unrequired quantity on the accounts of the consumer. Underneath the U.S. government, it'll be a direct responsibility of the government if there is an unclear and unapplied amount which has lied to an account for even more than 4 years.

Therefore it does have to do about risk, skills, knowledge the safety of information. All above theory helps explain everything which enables the execution of operations as well as, as project manager, we have to track input and output information. we need to charge, past due, credits, debits, PD percent every week and month, seeing the company's pattern, and also transform policies as to how the trend or even the forecast can enhance.

Write a program to sort the (name, age, score) tuples by descending order where name is string, age and score are numbers. The sort criteria is: 1: Sort based on name 2: Then sort based on age 3: Then sort by score The priority is that name < age < score. If the following tuples are given as input to the program: [('John', '20', '91'), ('Jason', '21', '85'), ('Jony', '17', '91'), ('Johny', '17', '93'), ('Tom', '19', '80')]\

Answers

Answer:

The program in Python is as follows:

from operator import itemgetter

m = int(input("Number of records: "))

print("Name, Age, Score")

my_list =[]

for i in range(m):

   user_details = input()

   my_list.append(tuple((user_details.split(","))))

my_list.sort(key =  itemgetter(0, 1, 2))        

print("Sorted: ", my_list)

Explanation:

This imports the operator function from itemgetter

from operator import itemgetter

This gets the number of records, m

m = int(input("Number of records: "))

This prints the format of input

print("Name, Age, Score")

This initializes the list of tuples

my_list =[]

This iterates through m

for i in range(m):

This gets the details of each person

   user_details = input()

This appends the details to the tuple

   my_list.append(tuple((user_details.split(","))))

This sorts the tuple

my_list.sort(key =  itemgetter(0, 1, 2))        

This prints the sorted tuple

print("Sorted: ", my_list)

Answers

Answer:

Explanation:

The following code is written in Python. It creates a Person class and creates the constructor which takes in the name of the person for that instance, as well as a greeting method which outputs the desired "Hi, my name is" string with the name of that person. The output of the code can be seen in the attached picture below. I have created a person object called John and called the greeting method so that you can see the output.

class Person:

   name = ''

   def __init__(self, name):

       self.name = name

   def greeting(self):

       print('Hi, my name is ' + self.name)

The code containing the Person class definition and the greeting is found in the attached image

The Person class has a single instance field name that stores the name of the person.

The instance initializer, __init__, accepts an argument, name, and saves the value in the name attribute of the Person class.

The Person class also has a greeting method that is called by the main code segment. The main code segment creates a Person object, and calls it in the print function to display the greeting with the person's name.

Explanation:

This defines the calcPyramidVolume method

double calcPyramidVolume(double baseLength, double baseWidth, double pyramidHeight){

This calls the calcBaseArea method to calculate the base area of the pyramid

   double baseArea = calcBaseArea(baseLength, baseWidth);

This calculates the volume

   double volume = baseArea * pyramidHeight;

This returns the volume

   return volume;
