public static int

sumTwoLowestElements(int[] numbers)

{

PriorityQueue values = new PriorityQueue<>();

The chart shows changes in sea level from 1995 to 2013. According to the chart, sea levels rose at an average annual rate of 3.2
MariettaO [177]

Answer:

Did the global surface temperature increase steadily from 1995 to 2013?

Did sea ice extent in polar regions reduce because of melting from 1995 to 2013?

Explanation:

Only two questions are directly related to global warnings increasing sea levels:

  • Did the global surface temperature increase steadily from 1995 to 2013? Increasing temperature of the Earth's surface is actually what warming means.
  • Did sea ice extent in polar regions reduce because of melting from 1995 to 2013? If the polar ice melts then the sea levels will rise.

The other three questions were about the negative effects of rising sea levels, but not what could cause them.

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.
