Write a program that includes the following while loops.
Input radius (double) values and prints the diameter, circumference, and area of a circle. The loop will stop executing when a 0 or negative value is entered. Declare a global constant for PI, where PI = 3.14159265. Be sure and echo the input and display all output to 3 decimal places.
a second while loop that works as above, but instead asks the user if they want to enter radius (Y/N). What happens if you enter a negative radius?
Input temperatures until 999 and print whether above or below freezing.
Input temperatures until 999 and count number above and below freezing.
Input temperatures until 999 and print the average temperature.
Ask user if they want to enter a temperature and print whether above or below freezing.
a while loop that repeatedly enters test scores (integer) (pick a sentinel) and counts the numbers of As, Bs, Cs, Ds, and Fs and also prints the average test score.

Answer:

a modulator

Explanation:

Modulation can be defined as the conversion of digital signals into an analogue signal while transmitting it over a line. Similarly, demodulation is the conversion of analogue signal into a digital signal.

AM is an acronym for Amplitude Modulation and it's refers to a process that is typically used for coding sounds such as voices and music for transmission from one point to another.

On the other hand, FM is an acronym for frequency modulation used for the propagation and transmission of sound waves.

Basically, these two forms of modulation are used for broadcasting in radio transmission.

In Radio transmission, a modulator is an electronic device that is designed to superimpose a low frequency information onto a high frequency signal for transmission. Also, the high frequency is typically the carrier in the radio transmission process.

Answer:

Explanation:

The following code is written in Java, it creates and tests the findMax() method with the test inputs provided in the question. The method loops through asking the user for inputs, if a positive number is passed it checks if it is larger than the previous numbers and if so, saves it in a variable called max. Otherwise it breaks the loop and returns the variable max. The test output can be seen in the attached picture below.

import java.util.Scanner;

class Brainly {

   public static void main(String[] args) {

       System.out.println("Max number is: " + findMax());

   }

   public static int findMax() {

       int max = 0;

       Scanner in = new Scanner(System.in);

       while (true) {

           System.out.println("Enter a number: ");

           int num = in.nextInt();

           if (num >= 0) {

               if (num > max) {

                   max = num;

               }

           } else {

               break;

           }

       }

       return max;

   }

}

Answer:

import java.util.Scanner;

public class LabProgram {

  public static void main(String[] args) {

      System.out.println(findMax());

  }

  public static int findMax() {

      int max = 0;

      Scanner in = new Scanner(System.in);

      while (true) {

          int num = in.nextInt();

          if (num >= 0) {

              if (num > max) {

                  max = num;

              }

          } else {

              break;

          }

      }

      return max;

  }

float avg;//defining floating point variable

cout<<"Please input the number of temperatures to be read: ";//print message

cin>>n;//input integer value

if(i>10)//use if to check array length greater than 10

return -1;//return integer value -1

for(j=0;j<n;j++)//defining loop to input value

{

cout<<"Input temperature: "<<endl;//print message

cin>>a[j];//holding value in loop

}

for(i=0;i<n-1;i++)//defining loop to compare array value

{

for(j=i+1;j<n-1;j++)//defining loop to compare array value

{

if(a[i]>a[j])//use if to compare array values

{

   //swapping

temp=a[j];//holding array value in temp

a[j]=a[i];//holding value in first index of array  

a[i]=temp;//holding temp value

}

}

}

max=min=a[0];//holding max value  

for (i = 0; i < n; i++)//defining loop to compare array value

{

if (a[i] > max)//use if to compare max array value

{

max = a[i];//holding max array value

}

else if (a[i] < min)//use else if to compare min array value

{

min = a[i];//holding min array value

}

}

for(i=0;i<n;i++)//use loop to add array value

sum=sum+a[i];//adding array value

avg=(float) sum/n;//calculating avg of the array

std::cout.setf(std::ios::fixed);//using namespace

std::cout.precision(2);//using precision method

cout<<"The average temperature is: "<<avg<<endl;//print avg value with message

cout<<"The highest temperature is: "<<max<<endl;//print max value with message

cout<<"The lowest temperature is: "<<min<<endl;//print min value with message

return avg;//return avg value

}

int main()//defining main method

{

float k;//defining float variable

k=temperatures();//calling method  

}

Output:

Please find the attached file.

Explanation:

In this code, a method "temperatures" is declared that defines the integer and float variable in which "n, array" is used to store the array value and inside the method min and max variable is declared that use the conditional statement to store its value.

Outside the main method, a floating-point variable "k" is declared that calls the method and stores its value.  

Answer:

The operation that will occur first is D5*C6 (multiplication).

Explanation:

Excel’s default order of operator precedence mandates that Excel perform multiplication before addition and substraction. If you want the addition or substraction to be performed before multiplication or division, they must be in parentheses.

The order of operations in exel is:

1. Evaluate items in parentheses.

2. Evaluate ranges (:).

3. Evaluate intersections (spaces).

4. Evaluate unions (,).

5. Perform negation (-).

6. Convert percentages (%).

7. Perform exponentiation (^).

8. Perform multiplication (*) and division (/), which are of equal precedence.

9. Perform addition (+) and subtraction (-), which are of equal precedence.

10. Evaluate text operators (&).

11. Perform comparisons (=, <>, <=, >=).

Answer:

ItemName=input("Enter the name of the item purchased: ")

PoundPrice=input("Enter the price of an item per pound: ")

Pound=input("Enter the weight in pound: ")

4 * 10^9

2.7 * 10^-8

6.776 * 10^7

9.05*10^4

5.409*10^5

9.04 * 10^-3

3.2 * 10^-2

5.12 * 10^8

Explanation:

1. 4,000,000,000

4 * 1,000,000,000 = 4 * (10*10*10*10*10*10*10*10*10) = 4 * 10^9

2. 0.000000027

27 * 10^-9 = 2.7 * 10^-8

0.000000027 = 2.7 * 10^-8

3. 67,760,000 = 6776 * 10000

6776 * 10000 = 6776 * 10^4

6776 * 10^4 = 6.776 * 10^3 * 10^4 = 6.776 * 10^7

4. 90,500

905 * 100 = (9.05 * 100) * 100

(9.05*100) * 100 = 9.05 * 10^2 * 10^2 = 9.05*10^4

5. 540,900

5409 * 100 = (5.409 * 1000) * 100

(5.409*1000)*100 = 5.409*10^3 * 10^2

5.409*10^3 * 10^2 = 5.409*10^5

6.) 0.00904

0.00904 = 904 * 10^-5

904 * 10^-5 = 9.04 * 10^-3

7. 0.032

32 * 10^-3 = 3.2 * 10^-2

8. 512,000,000

512 * 1000000

512 * 10^6 = 5.12 * 10^2 * 10^6 = 5.12 * 10^8

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

//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));

} }

Answer:

The modified program in Java is as follows:

import java.util.*;

public class Main{

public static void main(String[] args) {

    Scanner input = new Scanner(System.in);

 int arrowHeadWidth, arrowBaseWidth, arrowBaseHeight;

 System.out.print("Head Width: "); arrowHeadWidth = input.nextInt();

 System.out.print("Base Width: "); arrowBaseWidth = input.nextInt();

 System.out.print("Base Height: "); arrowBaseHeight = input.nextInt();

 while (arrowHeadWidth <= arrowBaseWidth) {

       System.out.print("Head Width: "); arrowHeadWidth = input.nextInt();

 System.out.print("Base Width: "); arrowBaseWidth = input.nextInt();      }

 for(int i = 0; i<arrowBaseHeight; i++){

     for(int j = 0; j<arrowBaseWidth;j++){

         System.out.print("*");        }

         System.out.println();    }

 for(int i = arrowHeadWidth; i>0;i--){

     for(int j = 0; j<i;j++){

         System.out.print("*");        }

         System.out.println();    }

}

}

Explanation:

This declares the arrow dimensions

 int arrowHeadWidth, arrowBaseWidth, arrowBaseHeight;

This get input for the head width

 System.out.print("Head Width: "); arrowHeadWidth = input.nextInt();

This get input for the base width

 System.out.print("Base Width: "); arrowBaseWidth = input.nextInt();

This get input for the base height

 System.out.print("Base Height: "); arrowBaseHeight = input.nextInt();

This loop is repeated until the head width is greater than the base width

 while (arrowHeadWidth <= arrowBaseWidth) {

       System.out.print("Head Width: "); arrowHeadWidth = input.nextInt();

 System.out.print("Base Width: "); arrowBaseWidth = input.nextInt();      }

This iterates through the base height

 for(int i = 0; i<arrowBaseHeight; i++){

This iterates through the base width

     for(int j = 0; j<arrowBaseWidth;j++){

This fills the base

         System.out.print("*");        }

This prints a new line

         System.out.println();    }

These iterate through the arrow head

 for(int i = arrowHeadWidth; i>0;i--){

     for(int j = 0; j<i;j++){

This fills the arrow head

         System.out.print("*");        }

This prints a new line

         System.out.println();    }

The question above is missing many details and are actually various questions in one. I will answer each one seperately below...

A. The piece of code to get the ID in this code snippet that needs to replace XXX would be the following ... System.out.println("Student ID: " + s.getID());

B. A static main() can declare and create objects. Once these objects are created their instance methods can then be called.

C. Integer score1 = 72;

    int score2 = 85;

    Character grade = 'C';

     In the above code snippet, the information stored in score1, score2, and grade are the following... obj reference, 85, obj reference. This is becasue both Integer and Character are classes and the values being passed to their variables are referencing that object class, while score2 is a primitive type of int and is therefore simply a number.

D. The statement that is true is ... Contents of a Double instance can be modified after initialization. Objects can be modified by calling its setter methods after initializing it.

Noise pollution.

Explanation:

Noise pollution is too loud noise that is harmful to health or that significantly reduces the comfort of the environment or significantly impairs work. Noise pollution arises, for example, from traffic and work machines, as well as from noisy events such as open-air concerts. Noise pollution can also arise from industrial plants (such as wind turbines, rock crushers), work machines (such as cargo handling equipment in ports and other sites), individual machines and equipment (such as leaf blowers, clearing and chainsaws, air conditioners), water pumps) and other noise sources. The noise of the work machines also causes inconvenience to the user of the device if the source of the noise is close to the hearing system of the machine operator.
