Answer:
C) 1/60 Hz
Explanation:
The frequency is equal to the reciprocal of the period:
[tex]f=\frac{1}{T}[/tex]
where T is the period.
The period is the time the object takes to do one complete cycle. For the second hand, the period is
T = 60 s
Since this is the time it takes to complete one cycle. Therefore, its frequency is
[tex]f=\frac{1}{60 s}=\frac{1}{60}Hz[/tex]
