Explanation:
import java.io.*;
import java.util.Scanner;
public class Winners {
public static void main(String args[]) throws IOException {
Scanner sc = new Scanner(new File("WorldSeriesWinners.txt"));
String commands[] = new String[100000];
int c = 0;
while (sc.hasNextLine()) {
String input = sc.nextLine();
System.out.println(input);
if (input.isEmpty())
continue;
commands[c++] = input;
}
sc.close();
Scanner keyboard = new Scanner(System.in);
System.out.println("Enter the name of a team: ");
String name = keyboard.nextLine();
int count = 0;
for (int i = 0; i < c; i++) {
if (commands[i] != null) {
if (commands[i].equals(name)) {
++count;
}
}
}
if(count!=0)
System.out.println(name + " has won the World Series in the time period from 1903 through 2018 " +count + " number of times" );
else
System.out.println("Team with name "+name+ " does not exists");
}
}
Answer:
- <u>1,000W</u> (rounded to one significant figure)
Explanation:
I will answer in English.
The question is:
- <em>What is the power of a filament lamp that connects to the 220 V network, knowing that it has a resistance of 50 ohms?</em>
<em />
<h2>Solution</h2>
<em />
<em>Power</em>, <em>voltage</em>, <em>resistance</em>, and current, are related by either of the following equations:
Where:
- R is resistance in ohms (Ω)
- V is voltage in volts (V), and
- I is current in amperes (A)
Since you know the voltage (<em>220V</em>) and the resistance (<em>50Ω</em>), you can use the last equation:
Since the magnitude 50Ω has one significant figure, your answer should be rounded to one significant figure. That is <u>1,000W.</u>
