1440 Times a day (Also how many minutes that are in a day)
The second hand on the clock circles 420 times in 7 hours.
The second hand goes around once.
the second hand
Because it counts seconds.

The second hand on the clock circles 420 times in 7 hours.
The second hand goes around once.
The hour hand goes around the clock twice in one day, the minute hand goes around 24 times, and the second hand makes 1440 revolutions. So, in total, all three hands go around the clock a combined total of 1488 times in one day.
the second hand
Yes.
On a clock the hour hand makes two full rotations. Which means it goes around the clock two times.
A clock's second hand makes one complete revolution each minute. Thus, by definition, it is rotating at one revolution per minute or one RPM. That's its "rotational velocity" and it is the same no matter how big or small the clock might be. The actual velocity that the tip of the second hand might trace out as it revolves around the center of the clock will vary with the length of the second hand. The longer the hand, the faster the tip moves around the circumference.
72 times
The minute hand revolves around the clock face ONCE every hour. Therefore the hand would revolve around the clock 24 time in one day.
Once

If we define a day as 24 hours, the minute hand moves around the clock face once an hour. 24 times.
