1 rev/minute = 1/60 rev/second = 0.0167 Hz (rounded)
1/60Hz
Sometimes, it is called a sweep hand, but the hands on a clock usually are called hour, minute, and second.
What do you mean with "motion of the entire second hand"? Please bear in mind that different parts of the hand move at different speeds. The closest thing to a "motion of the entire second hand" might be the motion of its center of mass. In this case, the answer is clearly "no". The center of mass is closer to the center than the tip, and moves slower.
It depends on the motor used to run the clock.An electric motor can drive the second hand at constant velocities. A mechanical motor has a little pendulum in it. It swings back and forth once per second, and every time it swings it moves the second hand.
essentially yes if u want a near exact time
pi (there are 2 pi radians in a full circle) [or 3.14159]
rotation
No the 'second hand' of a clock has a higher velocity, it makes one rotation each minute, while the minute hand makes on rotation each hour and the hour hand makes one rotation every 12 hours.
the second hand
1/3600 Hz
The second hand on the clock circles 420 times in 7 hours.
The angular velocity of the second hand of a clock is pi/30 radians per second.
One revolution per hour.
Because it counts seconds.
Sometimes, it is called a sweep hand, but the hands on a clock usually are called hour, minute, and second.
Because it points at the seconds? hours minutes seconds
its least count will be one second
put clock oil on the second hand.
