Answer:
[tex]\frac{1}{60}Hz[/tex]
Explanation:
The frequency of the second hand of a clock is given by
[tex]f=\frac{1}{T}[/tex]
where T is the period of the second hand (the time it takes to complete one cycle).
The period of the second hand is 60 seconds:
T = 60 s
Therefore, its frequency is
[tex]f=\frac{1}{60 s}=\frac{1}{60}Hz[/tex]
