A sample containing 4.30 g of O2 gas has an initial volume of 13.0 L. What is the final volume, in liters, when each of the following changes occurs in the quantity of the gas at constant pressure and temperature.

A sample of 200 g of O, is removed from the 4.30 g of O, in the container.​

Answers

Answer 1

Answer:

Total amount of O₂ occupy volume = 76.50 L

2 .30 gm O₂ occupy volume = 7.48 L

Explanation:

We konw that,

Molar mass of O₂ = 31.9988 gm / mol

1 mole of O₂ = 31.9988 gm

Sample of oxygen = 0.600 mole

Computation:

0.600 mole = 31.9988 × 0.600

0.600 mole = 19.199 gm

Total amount of O₂ = 4.30 + 19.199

Total amount of O₂ = 23.499 gm

Total amount of O₂ occupy volume = 14 × 23.499/4.30

Total amount of O₂ occupy volume = 76.50 L

Total gm of O₂ = 4.30 - 2.00= 4.30 gm

2 .30 gm O₂ occupy volume = 14 × 2.30/4.30

2 .30 gm O₂ occupy volume = 7.48 L

Suppose that a server sends four packets of audio data, in 15 seconds each. The first is sent by the server exactly at noon (12:00:00), while each of the three successive packets is sent immediately after the completion of its predecessor. The client, on the other hand, receives the four packets beginning at 12:00:03, 12:00:20, 12:00:41, 12:00:59 respectively. What is the smallest delayed wait time (buffer) in seconds that would ensure the client had seamless playback (i.e. each packet plays immediately after the previous one ends)?

Answers

Answer:

15

Explanation:

for seamless playback each packet should be played before their predecessor so

4th packet will start at 12:01:03

3rd packet will start at 12:00:48

2nd packet will start at 12:00:33

1st packet will start at 12:00:18

as first packet arrives at 12:00:03 so wait time is 15 seconds for seamless playback

But she wants to begin saving money for her trip now. Which of the following is the most effective way for Velma to save money each month?

Answers

This question is incomplete because the options are missing; here are the options for this question:

Which of the following is the most effective way for Velma to save money each month?

A. Automatically reroute a portion of her paycheck to her savings account.

B. Manually deposit 10% of her paycheck in her savings account.

C. Pay all of her bills and then place the remaining money in her savings account.

D. Pay all of her bills and then place the remaining money in her piggy bank.

The correct answer to this question is A. Automatically reroute a portion of her paycheck to her savings account.

Explanation:

In this case, Velma needs to consistently save money for her vacation as this guarantees she will have the money for the trip. This means it is ideal every month she contributes consistently to her savings for the vacation.

This can be better be achieved by automatically rerouting a part of her paycheck for this purpose (Option A) because in this way, every month the money for the vacations will increase and the amount of money will be consistent, which means Velma will know beforehand the money she will have for the vacation. Moreover, options such as using a piggy bank or paying the bills and using the rest for her savings, do not guarantee she will contribute to the savings every month, or she will have the money she needs at the end.

Define the instance method inc_num_kids() for PersonInfo. inc_num_kids increments the member data num_kids. Sample output for the given program with one call to inc_num_kids():

Answers

Answer:

This is the instance method inc_num_kids()

def inc_num_kids(self):

       self.num_kids += 1

Explanation:

The first line is the definition of function inc_num_kids() which has a parameter self. self is basically an instance of  class PersonInfo

self.num_kids += 1 this statement incremented the data member num_kids by 1. This means that the instance method inc_num_kids, using instance self, increments the value of num_kids data member by 1.

The complete program is as following:

class PersonInfo:  #class name PersonInfo

   def __init__(self):   #constructor of the class

       self.num_kids = 0  # data member num_kids

   def inc_num_kids(self):  # method inc_num_kids

       self.num_kids += 1  #increments num_kids by 1

person1 = PersonInfo()  #creates object person of class PersonInfo

print('Kids:', person1.num_kids)  # prints num_kids value before increment

person1.inc_num_kids()  #calls inc_num_kids method to increment num_kids

print('New baby, kids now:', person1.num_kids) #prints the value of num_kids after increment by inc_num_kids method

The person1 object first access the initial value of num_kids initialized by the constructor. So the first value of num_kids is 0. self.num_kids = 0  This statement assigns the value 0 to num_kids data member. Next the method inc_num_kids() using the object person1. Now when this method is called the value of data member num_kids is incremented to 1.

So previously the value was 0 which now increments by 1 and becomes 1. Last print statement displays this new value which is incremented by the inc_num_kids() method.

Hence the output is:

Kids: 0

New baby, kids now: 1

The program along with its output is attached.

In this exercise we have to use the knowledge of computational language in python to describe a code, like this:

The code can be found in the attached image.

To make it easier the code can be found below as:

class PersonInfo:  

  def __init__(self):  

      self.num_kids = 0  

  def inc_num_kids(self):  

      self.num_kids += 1  

person1 = PersonInfo()

print('Kids:', person1.num_kids)  

person1.inc_num_kids()

print('New baby, kids now:', person1.num_kids)

Explanation:

The first line imports the string module into the program

The functipn easyCrypto() starts here

def easyCrypto(inputstring):

This line iterates through each character in the input string

      for i in range(len(inputstring)):

The try except handles the error in the program

             try:

This line gets the index of the current character (lower case)

                    ind = string.ascii_lowercase.index(inputstring[i])

This line adds 1 to the index

                    pos = ind+1

This line checks if the character is at even position

                    if pos%2 == 0:

If yes, it returns the alphabet before it

                           print(string.ascii_lowercase[ind-1],end="")

                    else:

It returns the alphabet after it, if otherwise

                           print(string.ascii_lowercase[ind+1],end="")

The except block does the same thing as the try block, but it handles uppercase letters

             except:

                    ind = string.ascii_uppercase.index(inputstring[i])

                    pos = ind+1

                    if pos%2 == 0:

                           print(string.ascii_uppercase[ind-1],end="")

                    else:

                           print(string.ascii_uppercase[ind+1],end="")

The conversion of symbolic op codes such as LOAD, ADD, and SUBTRACT to binary makes use of a structure called the ____.

Answers

Answer:

Op code table.

Explanation:

In Computer programming, an Op code is the short term for operational code and it is the single instruction which can be executed by the central processing unit (CPU) of a computer.

The conversion of symbolic op codes such as LOAD, ADD, and SUBTRACT to binary makes use of a structure called the Op code table. The Op code can be defined as a visual representation of the entire operational codes contained in a set of executable instructions.

An Op code table is arranged in rows and columns which basically represents an upper or lower nibble and when combined depicts the full byte of the operational code. Each cells in the Op code table are labeled from 0-F for the rows and columns; when combined it forms values ranging from 00-FF which contains information about CPU cycle counts and instruction code parameters.

Hence, if the operational code table is created and sorted alphabetically, the binary search algorithm can be used to find an operational code to be executed by the central processing unit (CPU).

Write a small program that asks the user how many asterisks it should print out. The user responds with a number, then the program prints that number of asterisks.

Answers

Answer:

I am writing a C++ program. Let me know if you want the program in some other programming language.

#include <iostream> //to use input output functions

using namespace std; // to identify objects like cin cout

int main(){  //start of main() function body

int n; // number of asterisks

cout<<"how many asterisks do you want to print? "; //asks user how many asterisks it should print

   cin>>n; // reads the value of number of asterisks that user want to print

   for( int i=0; i< n; i++)    { //loop to display the number of asterisks in output

       printf("*");    } } // print * asterisks

Explanation:

I will explain how the for loop works.

Suppose the user entered 3 as number of asterisks that user wants to print.

So n=3

Now for loop has a variable i that is initialized to 0. For loop checks if the value of i is less than that of n. It is true because i=0 and n=3 and 0<3. So the body of the loop executes. This prints the first asterisk *

Then the value of i is incremented to 1 and becomes i=1

At next iteration loop again checks if value of i is less than n. It is true because i=1 and n=3 and 1<3. So the body of the loop executes. This prints the second asterisk **

Then the value of i is incremented to 1 and becomes i=2

At next iteration loop again checks if value of i is less than n. It is true because i=2 and n=3 and 2<3. So the body of the loop executes. This prints the third asterisk ***

Then the value of i is incremented to 1 and becomes i=3

At next iteration loop again checks if value of i is less than n. This time it evaluates to false because i=3 and n=3 so 3=3. So the loop ends and the output is

***

Modularize the program by adding the following 4 functions. None of them have any parameters. void displayMenu() void findSquareArea() void findCircleArea() void findTriangleArea() To do that you will need to carry out the following steps: Write prototypes for the four functions and place them above main. Write function definitions (consisting of a function header and initially empty body) for the four functions and place them below main. Move the appropriate code out of main and into the body of each function. Move variable definitions in main for variables no longer in main to whatever functions now use those variables. They will be local variables in those functions. For example, findSquareArea will need to define the side variable and findCircleArea will need to define the radius variable. All of the functions that compute areas will now need to define a variable named area. Move the definition for the named constant PI out of main and place it above the main function. In main, replace each block of removed code with a function call to the function now containing that block of code.

cout<<"\nArea of Triangle: "<<area<<endl;  //displays area of triangle

}

Explanation:

The program is modified as above. The prototypes for the four functions that are named as :

void displayMenu();  to display the Menu of choices and call relevant function to compute area

void findSquareArea();  To compute area of square

void findCircleArea(); To compute area of circle

void findTriangleArea();  To compute area of triangle

Note that these methods have no parameters and their return type is void. These 4 methods prototypes are placed above main() function.

Next the function definitions (consisting of a function header and initially empty body) for the four functions are written and placed below main() For example definition of findTriangleArea() is given below:

void findTriangleArea()

{

}

Next the code in the main is moved to the relevant methods. Then variables selection=0;  is moved to displayMenu method,  radius=0.0 to findCircleArea method , side=0; to findSquareArea float area=0.0;  to each method, float height=0.0;  and float base=0.0; to findTriangleArea method.

The relevant code moved to each method is shown in the above code.

The definition for the named constant PI is moved out of main and placed above the main function. const keyword before datatype of PI variable shows that PI is declared constant and its value is initialized once only to 3.14159.

Answers

Answer:

Early in the history of technology, the development of tools and machines was based on technical know-how versus scientific knowledge as is done today.

Explanation:

In the era prior to technological development, men had a basic and at times rudimentary manufacturing development, based on artisan processes that developed their tools and machinery by hand, without any type of automation or mass production rules.

Thus, each part or tool was manufactured in a unique way, which required a broad mastery of the production process by the manufacturer. This is how the first professions began to emerge, such as blacksmiths for example, who mastered the technique of manufacturing different implements and carried them out without any scientific knowledge.
