It is real I hoped this help you
Answer:
import java.util.Arrays;
import java.util.Scanner;
public class num1 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.println("Enter length of the array:");
int len = in.nextInt();
double [] temps = new double[len];
double avgTem;
int k =0;
double total = 0;
for( k=0; k<temps.length; k++){
System.out.println("Enter values for the array");
temps[k]=in.nextDouble();
}
System.out.println("The Arrays contains the following values");
System.out.println(Arrays.toString(temps));
// Computing the average of the values
for(k=0; k<temps.length; k++){
total = total+temps[k];
}
avgTem = total/(temps.length);
System.out.println("The average Temperature is: "+avgTem);
}
}
Explanation:
- Using Java programming language
- Import the Scanner class to receive user input
- Prompt User for the length of the Array, receive and store in a variable len;
- Declare a new double array of size len double [] temps = new double[len];
- Using a for loop, continually prompt user to enter values into the array
- Display the values of the array using Java's Arrays.toString method
- Use another for loop to add up all the elements in the arraay and store in the variable called total
- Outside the second for loop calculate the average avgTem = total/(temps.length);
- Display the average temp.
convection requires a medium is not the main difference, it is simply the most obvious aspect of what is a fundamentally different mechanism for transfering energy. Convection is the transfer of energy by movement of a medium, whereas radiation is the transfer of energy by, well, thermal radiation. Conduction also requires a medium, but, again, it is a fundamentally different mechanism than either convection or radiation; in this case it is the transfer of energy through a medium.
Unfortunately, analogies are hard but if you can visualize the particles involved, it would help. Picture the red hot iron you mentioned. On a molecular level, the material is emitting lots and lots of photons (hence why it is glowing red). The creation of these photons takes energy; energy from the heat of the iron. These photons leave the iron, pass through the environment, and eventually collide with some other object where they are absorbed and deposit their energy. This is radiative heat transfer. If that energy is deposited on your retina or a CCD (like in a digital camera), an image forms over time. This is how infrared goggles work and they would work equally well in high vacuum as here on earth.
In conduction, the next simplest example, there is no generation of photons (physics nerds forgive me for the sake of simplicity). The individual atoms in the object are vibrating with heat energy. As each atom gains energy from it's more energetic neighbors, so it gives up energy to its less energetic ones. Over time, the heat "travels" through the object.
In convection, the molecules of gas near the object gain energy, like in the conduction case, but those same molecules that gained energy then travel through the environment to some other location where they then give off their heat energy.
In summary:
radiation = generated and absorbed photonsconduction = molecules exciting their neighbors succesivelyconvection = molecules heated like in conduction, but then move to another location
