Rest the left-hand’s fingers on A,S, D, and F keys.
Rest the right-hand’s fingers on A,S, D, and F keys.
Rest the right-hand’s fingers on Q,W, E, and R keys.
Answer:
Rest the right-hand’s fingers on Q,W, E, and R keys.is the correct answer
Explanation:
the hours, minutes, and sections, and various operations to adjust the time. The framework for your
clock is in the Time class with the four methods you must complete.
1.) advanceOneSecondâ A user calls this method to advance the clock by one second.
a. When the seconds value reaches 60, it rolls over to zero.
b. When the seconds roll over to zero, the minutes advance.
So 00:00:59 rolls over to 00:01:00.
c. When the minutes reach 60, they roll over and the hours advance.
So 00:59:59 rolls over to 01:00:00.
d. When the hours reach 24, they roll over to zero.
So 23:59:59 rolls over to 00:00:00.
2.) compareTo â The user wants to know if a second time is greater than or less than the time
object called, assuming both are on the same date.
a. Returns -1 if this Time is before otherTime.
b. Returns 0 if this Time is the same as otherTime.
c. Returns 1 if this Time is after otherTime.
3.) add â Adds the hours, minutes, and seconds of another time (the offset) to the current time
object. The time should ârolloverâ if it exceeds the end of a 24 hour period.
4.) subtract â Subtracts the hours, minutes, and seconds of another time (the offset) from
the current time object. The time should âroll backâ if it precedes the beginning of a 24 hour
period.

Using the knowledge in computational language in JAVA it is possible to write a code that user calls this method to advance the clock by one second. When the seconds value reaches 60, it rolls over to zero.
public class Time
{
private int hours;
private int minutes;
private int seconds;
public void advanceOneSecond()
{
seconds++;
if(seconds >= 60)
{
seconds -= 60;
minutes++;
}
if(minutes >= 60)
{
minutes -= 60;
hours++;
}
if(hours >= 24)
hours -= 24;
}
public int compareTo(Time otherTime)
{
if(hours > otherTime.hours)
return 1;
else if(hours < otherTime.hours)
return -1;
else
{
if(minutes > otherTime.minutes)
return 1;
else if(minutes < otherTime.minutes)
return -1;
else
{
if(seconds > otherTime.seconds)
return 1;
else if(seconds < otherTime.seconds)
return -1;
else
return 0;
}
}
}
public void add(Time offset)
{
seconds += offset.seconds;
minutes += offset.minutes;
hours += offset.hours;
if(seconds >= 60)
{
seconds -= 60;
minutes++;
}
if(minutes >= 60)
{
minutes -= 60;
hours++;
}
if(hours >= 24)
hours -= 24;
}
public void subtract(Time offset)
{
if(offset.seconds > seconds)
{
minutes--;
seconds = seconds + 60;
}
seconds -= offset.seconds;
if(offset.minutes > minutes)
{
hours--;
minutes = minutes + 60;
}
minutes -= offset.minutes;
if(offset.hours > hours)
{

c. CRT
d. UPS
Answer: A) Battery backup
Explanation:
A battery backup are used to provide the source of power backup to various hardware components and desktop computers. In many cases, the devices are plugged into UPS ( uninterruptible power supply) for backup power and it is also depend upon the size of the UPS.
All the battery backups are located inside so that is why, the devices are heavy in weight. Usually, the battery backup front required additional button for performing various functions.
And the battery backup devices are manufacture by using the varying degree of backup abilities.
Answer:
public int RandNum();
* Assuming it returns an integer
Explanation:
I believe you mean to write the function header of randNum.
To write the header of the function, we need to specify its return type, name, parenthesis and parameters inside the parenthesis - if exist.
If it returns an integer it should have int, if it returns a double it should have double in the header. In the answer, I assumed it returns an integer.
The name is already given, RandNum
Since, the function does not take any parameter, inside of the parenthesis will be empty.
Answer:
The answer is below
Explanation:
There are cases where the use of a NULL value would be appropriate in a computer programming situation. These cases can be summarily described below:
The first case is in a situation where the value of the attribute of a certain element is known to exist, but the value can not be found
The second case is in a situation where the value of the attribute of a certain element is not known whether it exists or not.

Answer:
The largest safety threat to the ISS are the micrometeorite and orbital debris (MMOD) fires, impacts and toxic spills. These pose the biggest threat to the ISS astronauts.
Explanation:
The debris is as a result of collisions. An observation revealed that once a certain mass is passed, collisions give rise to more debris.
Another report revealed that the station has about 55% chance of being hit by tiny space rocks over a 10-year period. They can protected by installing new impact-protecting panels to the exterior of the station.
ISS means International Satellite Station.
