The answer would be to first check the normal voltage supply so that there is enough electric current flowing for the electric heating appliance to work or run.
Answer:
public class Calculator {
public double add(int a, int b){
return a+b;
}
public double substract(int a, int b){
return a-b;
}
public double multiply(int a, int b){
return a*b;
}
public double divide(int a, int b){
if(b>0){
return a/b;
}
else{
System.out.println("Cannot divide by zero");
}
return -1;
}
}
Explanation:
- Using Java Programming Language, the class Calculator is created. There are no fields (Instance variables) and no constructors since these are not required by the question.
- Four methods (functions) are created: add, substract, multiply and divide as specified in the question.
- Note the use of the if statement in the divide() to handle case of illegal division (by 0)

Answer:
The correct answer for the given question is option(A) i.e Global
Explanation:
The global variable is the variable which is declared outside the function The lifetime and scope of global variable in whole the program i.e "Globally" .They can be access anywhere in the program,however local variable are those which is declared inside the function .local variable are access inside that function only where it is declared.
Following are the example of Global variable.
#include <stdio.h> // header file
int t=9;// global variable declared outside the function
int main() // main function()
{
printf("%d",t); // display the value of t
return 0;
}
so the correct answer is Global.
Answer: D)add up the storage requirements for the operating system and all of the software applications currently installed.
Explanation:Hard disk drive (HDD) is the secondary hardware device for the storage of the data permanently. It can be used for storing data along with the videos, documents, pictures etc.
Hard drive can store data in a large amount as compared to any other drive and having varying capacity of data storage according to the data.The minimum space of the hard drive to be embedded in a system is calculated on the basis of the storage of files of operating system,software programs and other data.
So, option (D) is the correct option.
