The speed of sound depends on the material the sound is passing through. Below is the approximate speed of sound (in feet per se

german

Answer:

The Java Program for the given problem is as below. Directly copy the code and run it on your machine.

Explanation:

Refer the Screenshots attached for the output.

import java.io.BufferedReader;

import java.io.InputStreamReader;

public class TheSpeedOfSound {

public static void main(String[] s)

{

String medium;

double distance;

double time;

try{

BufferedReader choice = new BufferedReader(new InputStreamReader(System.in));

System.out.println("Enter one of the following: air, water, or steel: ");

medium = choice.readLine(); // reading input i.e. air, water or steel

//check for air water and steel

if (medium.equalsIgnoreCase("air") || medium.equalsIgnoreCase("water") || medium.equalsIgnoreCase("steel")){

System.out.println("Enter the distance the sound wave will travel: ");

distance = Double.parseDouble(choice.readLine()); // read distance value if it is air water or steel

switch (medium)

{

//if medium is air

case "air":

time = distance/1100;

System.out.print("It will take " + time + " seconds.");

break;

//if medium is water

case "water":

time = distance/4900;

System.out.print("It will take " + time + " seconds.");

break;

//if medium is steel

case "steel":

time = distance/16400;

System.out.print("It will take " + time + " seconds.");

break;

}

else{

System.out.print("Sorry, you must enter air, water, or steel.");

}

catch(Exception e){

e.printStackTrace();

Computers represent color by combining the sub-colors red, green, and blue (rgb). Each sub-color's value can range from 0 to 255

Effectus [21]

Answer:

<em>The programming language is not stated; However, I'll answer the question using C++ programming language, </em>

<em>This program uses comments for explanations </em>

<em>Program starts here</em>

#include<iostream>

using namespace std;

int main()

{

//Declare Array

int colorcode[3],graycode[3];

//Prompt user for color code

cout<<"Enter Color Code (One on a line)"<<endl<<"Inout Range is 0 to 255"<<endl;

for(int i = 0;i<3;i++)

{

ccode:

cout<<"Enter Color Code "<<i+1<<": ";

cin>>colorcode[i];

if(colorcode[i]<0 || colorcode[i]>255)

{

cout<<"Input Range is 0 to 255"<<'\n';

goto ccode;

}

//Initialize smallest to colorcode[0]

int smallest = colorcode[0];

//Determine smallest

for(int i = 0;i<3;i++)

{

if(colorcode[i]<smallest)

{

smallest = colorcode[i];

}

//Determine Graycode

for(int i = 0;i<3;i++)

{

graycode[i] = colorcode[i] - smallest;

}

//Display Result:

cout<<"Color Code: "<<"(";

for(int i = 0;i<3;i++)

{

if(i!=2)

{

cout<<colorcode[i]<<",";

}

else

{

cout<<colorcode[i]<<")"<<endl;

}

cout<<"Gray Code: "<<"(";

for(int i = 0;i<3;i++)

{

if(i!=2)

{

cout<<graycode[i]<<",";

}

else

{

cout<<graycode[i]<<")"<<endl;

}

return 0;

In which part of a presentation should you provide background information, ask a thoughtful question, or offer an interesting

makkiz [27]

The correct answer is A. Opening

Explanation:

In a presentation or the text, the opening is the first section that should allow the audience to understand what is the topic and focus. This is achieved through a hook that can include an interesting fact or a rhetorical question (a question that makes the audience think) because these two elements grab the attention of the audience. Additionally, after the hook, it is common to provide background information about the topic of the presentation, and finally, the speaker will state the main point or thesis statement. This occurs before the body of the presentation, which is the main section, and the closing, which is the last section. Thus, elements such as background information or an interesting fact are part of the opening.

mestny [16]

The conclusion sustains the thermogram will be that the windows are not energy efficient, but the roof stands energy efficient.

<h3>What is Thermography?</h3>

Thermography exists a noninvasive method that employs an infrared camera to develop pictures that depict patterns of heat and blood flow on or around the body's surface. A thermogram taken outside a house shows high quantities of thermal energy around the windows but not around the roof. The conclusion that supports the thermogram will be that the windows are not energy efficient, but the roof exists energy efficient.

Thermal energy (also named heat energy) is produced when a rise in temperature pushes atoms and molecules to move faster and collide with each other. The energy that reaches the temperature of the heated substance is named thermal energy. The term "thermal energy" exists utilized loosely in various contexts in physics and engineering. It can guide several different well-defined physical concepts.

The complete question is,

A thermogram taken outside a house shows high amounts of thermal energy around the windows but not around the roof.

Which conclusion supports the thermogram?

The windows and the roof are energy efficient.

The windows and the roof are not energy efficient.

The windows are not energy efficient, but the roof is energy efficient.

The windows are energy efficient, but the roof is not energy efficient.
