You are working on a graphical app, which includes multiple different shapes. The given code declares a base Shape class with an abstract area() method and a width attribute. You need to create two Shape subclasses, Square and Circle, which initialize the width attribute using their constructor, and define their area() methods. The area() for the Square class should output the area of the square (the square of the width), while for the Circle, it should output the area of the given circle (PI*width*width). The code in main creates two objects with the given user input and calls the area() methods.

Sample Input:
5
2

Sample Output:
25
12.566370614359172

The area of the square is 5*5=25, while the area of the circle is PI*2*2=12.566370614359172

Answers

Answer 1

A class can have multiple subclasses, where each of the subclasses function independently. The extend keyword will be used to pass attributes from the Shape class to the Square and Circle subclasses

To answer this question, I will make the following assumptions

The Shape class is already definedThe area() method of the Shape class is also definedLines that begin with // are comments, and these lines will be used to explain the code segment

//This creates the Square class

class Square extends Shape {

//The creates a constructor for width variable

Square(int length) {  this.width = length;  }

//This defines the area() method from the Square class

void area() {  

//This calculates and prints the area of the square

System.out.print(Math.pow(width,2));  } }

//This creates the Circle class

class Circle extends Shape {

//The creates a constructor for width variable

Circle(int radius){  this.width = radius;  }

//This defines the area() method from the Square class

void area(){

//This calculates and prints the area of the circle

System.out.println(Math.PI*Math.pow(width,2));

} }

Answers

Answer:

Following are the code to the given question:

For code 1:

start = int(input())#defining a start variable that takes input from the user end

end = int(input())#defining a end variable that takes input from the user end

if start > end:#use if that checks start value greater than end value

   print("Second integer can't be less than the first.")#print message

else:#defining else block

   while start <= end:#defining a while loop that checks start value less than equal to end value

       print(start, end=' ')#print input value

       start += 5#incrementing the start value by 5

   print()#use print for space

For code 2:

while True:#defining a while loop that runs when its true

   data = input()#defining a data variable that inputs values

   if data == 'Done' or data == 'done' or data == 'd':#defining if block that checks data value

       break#use break keyword

   rev = ''#defining a string variable rev

   for ch in data:#defining a for loop that adds value in string variable  

       rev = ch + rev#adding value in rev variable

   print(rev)#print rev value

Explanation:

In the first code two-variable "first and end" is declared that takes input from the user end. After inputting the value if a block is used that checks start value greater than end value and use the print method that prints message.

In the else block a while loop is declared that checks start value less than equal to end value and inside the loop it prints input value and increments the start value by 5.

In the second code, a while loop runs when it's true and defines a data variable that inputs values. In the if block is used that checks data value and use break keyword.

In the next step, "rev" as a string variable is declared that uses the for loop that adds value in its variable and prints its values.

perimeter = 4*a

print(area, perimeter)

Explanation:

Code written in python :

The first function named two, takes to arguments a and b ;

The sum of integers a and b is taken and displayed using ; print(a+b)

The product of integers a and b is taken and displayed using ; print(a*b)

Explanation:

The solution and the explanation could not be submitted directly. So,I added both as attachments

To print a rectangle based on the given number of rows and columns, you will use nested loops using the following code:

num_rows = int(input())

num_cols = int(input())

for i in range(num_rows):

   for j in range(num_cols):

       print('*', end=' ')

   print()

How can I print a rectangle using nested loops?

By using nested loops, you will iterate through each row and column to print the desired shape. The outer loop controls the rows while the inner loop controls the columns. Within the inner loop, the desired symbol or character, such as "*", is printed with the print() statement.

The end=' ' parameter is used to separate each character by a space. The outer loop then moves to the next row and the process continues until the desired number of rows and columns are printed forming a rectangle.

Explanation:

Required

Statements to print two random numbers between 100 and 149 (both inclusive)

First, the random numbers must be generated. From the template given, the random object, randGen, has been created.

The syntax to then follow to generate between the interval is:

randGen.nextInt(high-low) + low;

Where:

high = 149 and low = 100

So, the statement becomes:

randGen.nextInt(149 - 100) + 100;

randGen.nextInt(49) + 100;

Lastly, print the statements:

System.out.println(randGen.nextInt(49) + 100);

System.out.println(randGen.nextInt(49) + 100);

 int n, num;

 Scanner input = new Scanner(System.in);

 System.out.print("Number of inputs: ");

 n = input.nextInt();

 LinkedList<Integer> myList = new LinkedList<Integer>();

 for(int i = 0; i<n;i++){

     System.out.print("Input Integer: ");

     num = input.nextInt();

     while (num > 0) {

     myList.push( num % 10 );

     num/=10;

     }

     while (!myList.isEmpty()) {

         System.out.print(myList.pop()+" ");

     }

     System.out.println();

     myList.clear();

 }

}

}

Explanation:

This declares the number of inputs (n) and each input (num) as integer

 int n, num;

 Scanner input = new Scanner(System.in);

Prompt for number of inputs

 System.out.print("Number of inputs: ");   n = input.nextInt();

The program uses linkedlist to store individual digits. This declares the linkedlist

 LinkedList<Integer> myList = new LinkedList<Integer>();

This iterates through n

 for(int i = 0; i<n;i++){

Prompt for input

     System.out.print("Input Integer: ");

This gets input for each iteration

     num = input.nextInt();

This while loop is repeated until the digits are completely split

     while (num > 0) {

This adds each digit to the linked list

     myList.push( num % 10 );

This gets the other digits

     num/=10;

     }

The inner while loop ends here

This iterates through the linked list

     while (!myList.isEmpty()) {

This pops out every element of thelist

         System.out.print(myList.pop()+" ");

     }

Print a new line

     System.out.println();

This clears the stack

     myList.clear();

A capacitor of capacitance 102/π µF is connected across a 220 V, 50 Hz A.C. mains. Calculate the capacitive reactance, RMS value of current and write down the equations of voltage and current.

Answers

Answer:

The capacitive reactance will be "100Ω" and RMS value of current is "2.2 A". A further explanation is provided below.

Explanation:

Given:

[tex]C =\frac{10^2}{\pi}\times 10^{-6} \ F[/tex]

[tex]V_{RMS}=220 \ V[/tex]

[tex]f = 50 \ Hz[/tex]

Now,

The capacitive reactance will be:

⇒ [tex]X_c=\frac{1}{\omega C} =\frac{1}{2 \pi f C}[/tex]

                   [tex]=\frac{1}{2\times \pi\times 50\times \frac{10^{-4}}{\pi} }[/tex]

                   [tex]=100 \ \Omega[/tex]

RMS value of current will be:

⇒ [tex]I_{RMS}=\frac{V_{RMS}}{X_c}[/tex]

             [tex]=\frac{220}{100}[/tex]

             [tex]=2.2 \ A[/tex]

So that,

⇒ [tex]V_m=220\times \sqrt{2}[/tex]

         [tex]=311 \ V[/tex]

⇒ [tex]I_m=2.2\times \sqrt{2}[/tex]

         [tex]=3.1 \ A[/tex]

hence,

The equation will be:

⇒ [tex]\nu=311 sin31 \ 4t[/tex]

and,

⇒ [tex]i=3.1 sin(314t+\frac{\pi}{2} )[/tex]
