The Speed of Sound (Java Project. Please make it easy to understand. I'm a beginner at this. I believe we are supposed to use a
Ilya [14]

Answer:

The program of this question can be given as:

Program:

//import pacakge for user input.

import java.util.Scanner;

//define class  

public class SpeedofSound              

{

  public static void main(String a[]) //define main function

  {  

      //define variable.

      String medium;                            

      double distance,time=0;

      //creating Scanner class object for input from user.

      Scanner s=new Scanner(System.in);  

      //print message.

      System.out.printf("Enter medium(air,water or steel) : ");

      medium=s.nextLine();  //taking input.

      //print message.

      System.out.printf("Enter the distance that the sound will travel : ");

      distance=s.nextDouble(); //taking input.

      switch(medium) //checking condtion between range.

      {

          case "air":

                  time=distance/1100;         //apply formula

                  break;

          case "water":

                  time=distance/4900;            //apply formula

                  break;

          case "steel":

                  time=distance/16400;            //apply formula

                  break;

          default:

                  System.out.printf("Sorry, you must enter air,water or steel"); //error for invalid input of medium

                  System.exit(0);

      }

      System.out.printf("It take "+time+" seconds"); //print final answer.

  }

}

Output:

Enter medium(air,water or steel) : air

Enter the distance that the sound will travel : 200

It take 0.18181818181818182 seconds

Explanation:

In this program first, we import packages for user input. Then we declare the class in the class we declare all the variables and then we create the scanner class object. It is used for taking input from the user. Then we use the switch statement It is used for condition. It works between the ranges. In the switch statement, we apply all the formula that is given in the question. and at the last, we print the output using printf function in java.

Can you help me with these AP Computer Science Questions. (THIS IS DUE BY 1:30 PM today) you have to evaluate the Boolean Expres
vfiekz [6]

Answer + Explanation:

'and' -> both statements are 'True' to evaluate as 'True'.

'or' -> at least one statement is 'True' to evaluate as 'True'.

1. True (grade has the value of 82, so the statement evaluates to 'True').

2. True (Both statements are true, this expression evaluates to 'True').

3. False (Both statements are false, this expression evaluates to 'False').

4. True (the != operator means <em>not equal.</em> Since the 'name' variable holds the string 'Rumpelstiltskin', name != 'Rumpelstiltskin' evaluates to 'False'. The 'not' operator returns the opposite of the given Boolean expression, so this expression evaluates to 'True').

5. True (name == 'Rumpelstiltskin' evaluates to 'True', so this expression is true).

6. False (All statements evaluate to 'False').

7. True (All statements evaluate to 'True').

8. False (All statements evaluate to 'True' except for <em>not(x == - 3) </em>which evaluates to 'False', so the whole statement now becomes false).

9. True (<em>grade+5 < 90 and grade >= 80 </em>evaluates to 'True', so this whole expression becomes true).

10. True (<em>grade > 0 and x % 2 == 1 </em>evaluates to 'True')

Hope this helps :)
