Answer:

Answer:

The program to this question as follows:

Program:

public class DataTransmitter //defining class

{

double x=3.0; //define variable x.  

public static void sendDouble(double x) //define method sendDouble.

{

x=9.6; //change variable value

System.out.print("The value of x variable is :"+x); //print value.

}

public static void main(String[] args) //define main method

{

sendDouble(0.0); //calling function

}

}

Output:

The value of x variable is :9.6

Explanation:

The explanation of the above java program can be define as follows:

  • In the above java program a class is define that is "DataTransmitter" inside a class a double variable that is x is define which contain a double value that is "3.0".
  • In this class, a static method "sendDouble()" is defined. in the method, a double parameter is passed. inside a method, we change the variable value and print its value.
  • In main method is a sendDouble() function is called. In calling time a double value is passed in the function parameter.

Why does a CPU need Thermal Grease?

Answers

The CPU generates a lot of heat while doing its job, and if the CPU can't get rid of
the heat, that's very bad for the CPU.  (Scientists say the CPU 'fails'.  Engineers say
the CPU 'dies'.  Users say the CPU 'burns up'.)

If you look at the CPU in your computer, you'll see that it's mounted on a big black
piece of metal with lots of fins and grooves in it, called a "heat sink".  There may
also be a little fan blowing air past the heat sink, to help take heat away from it. 
The thermal grease carries heat from the CPU to the heat sink faster than if they
were just bolted together with nothing in between them.
