Answer:
class OddNumber
{
public static void main(String args[])
{
int n = 1000; //Store 1000 in Variable n typed integer
System.out.print("Odd Numbers from 1 to 1000 are:"); // Print headline of output window
for (int i = 1; i <= n; i++) //For loop to go through each number till end
{
if (i % 2 != 0) //check if number is even or odd.Not divisible by 2 without reminder means it is odd number
{
System.out.print(i + " "); //print odd numbers
}
}
}
}
Answer:
Power = 1920 Watts or 1.92 Kilowatts
Explanation:
Given the following data;
Resistance = 30 Ohms
Voltage = 240 Volts
To find power rating of the kettle;
Mathematically, the power consumption of an electric device is given by the formula;
Power = voltage²/resistance
Substituting into the formula, we have;
Power = 240²/30
Power = 57600/30
Power = 1920 Watts or 1.92 Kilowatts
