Answer:
Question 1:
int numUsers = scnr.nextInt();
Question 2:
public class OutputExample {
public static void main (String [] args) {
int numCars = 99;
Scannerscnr=new Scanner(System.in);
numCars=scnr.nextInt();
System.out.println("There are "+numCars+" cars");
return;
}
}
Question 3:
import java.util.Scanner;
public class Errors {
public static void main(String [] args) {
int userNum = 5;
System.out.println ("Predictions are hard. ");
System.out.print("Especially ");
System.out.print("about the future.");
System.out.println("Num is: "+userNum);
return;
}
}
Explanation:
In Question 1, the statement int numUsers = scnr.nextInt(); reads a new integer value from the keyboard and assigns it to the variable numUsers.
In question 2, Concatenation is used to format the print output.
In question 3, care is taken to fix each of the syntax errors (missing double quotes, semi-colon, concatenation)
Answer:
The major characteristics of computers are the following:
Speed : A powerful computer is capable of executing about 3 million calculations per second.
Accuracy : A computer's accuracy is consistently high; if there are errors, they are due to errors in instructions given by the programmer.
Reliability : The output generated by the computer is very reliable as long as the data is reliable.
Memory/Storage Capacity : The computer can store large volumes of data and makes the retrieval of data an easy task.
Versatility: The computer can accomplish many different things. It can accept information through various input-output devices, perform arithmetic and logic operations, generate a variety of outputs in a variety of forms, etc.
Automation: Once the instructions are fed into computer it works automatically without any human intervention.
Diligence: A computer will never fail to perform its task due to distraction or laziness.
Convenience: Computers are usually easy to access, and allow people to find information easily that without a computer would be very difficult.
Flexibility: Computers can be used for entertainment, for business, by people who hold different ideals or who have varied goals. Almost anyone can use a computer, and computers can be used to assist with almost any goal.

Misfiring seems to be a blanket term for spark plug inefficiencies and errors due to wrong gap configuration. Because of the small gap, the time <span>of the spark has less travel distance, it does not remain hot enough to ignite the air-fuel mixture that is needed to run the engine. </span>

Explanation:
There is no (as far as I know) way to turn a rocket you're not in control of using mechanical methods. The best way would be (if it's a heat seeking missile for instance) to use flares to lure it somewhere else.
If the rocket is controlled by a computer, it is hypothetically possible to take control of the rocket; however, because of the security, this is about as hard as trying to finding the key of some well encrypted message : it's nearly impossible.
