The global positioning system (GPS) is a space-based radio-positioning and time-transfer system. GPS satellites transmit signals to proper equipment on the ground. These signals provide accurate position, velocity, and time (PVT) information to an unlimited number of users on ground, sea, air, and space.
Answer: This is a python code
def lightyear():
rate=3*100000000 //speed of light
seconds=365*24*60*60 //number of seconds in 1 year
return str((rate*seconds)/1000)+" km" //distance=speed x time
print(lightyear()) //will print value of light hear in kilometers
OUTPUT :
9460800000000.0 km
Explanation:
In the above code, there is a variable rate, which stores the speed of light, i.e. distance traveled by light in 1 second which is in meters. Another variable is seconds, which store the number of seconds in 1 year, which is no of days in 1 year multiplied by the number of hours in a day multiplied by the number of minutes in an hour multiplied by the number of seconds in a minute. Finally, distance is speed multiplied by time, so distance is printed in kilometers and to convert distance in kilometers it is divided by 1000.
Answer:
the user cannot use a computer system without hardware and software
Answer:
public static void printDottedLine(){
System.out.print(".....\n");
}
Explanation:
This method returns nothing so its return type is void
It also accepts no parameters so the argument list is empty
When called it executes the System.out.print(".....\n"); which prints out 5 dots
See a complete program below:
public class TestClock {
public static void main(String[] args) {
printDottedLine();
}
public static void printDottedLine(){
System.out.print(".....\n");
}
}
