The frequency is given as 0.996
How to get the frequency
Length(L) = 0.25 meters
For a simple pendulum, the time period (T) is determined by the formula:
![\[ T = 2π * \left((√(L))/(√(g))\right) \]](https://img.qammunity.org/2021/formulas/physics/high-school/twh2tb7k5hmgp0sxzb178khlxrzqnatq1p.png)
Given Length(L) = 0.25 m and acceleration due to gravity (g) = 9.80 m/s²:
![\[ T = 2π * \left((√(0.25))/(√(9.80))\right) \]](https://img.qammunity.org/2021/formulas/physics/high-school/tga0rtpcci4uw8wzoignomzjx92ukcyz4w.png)
![\[ T = 1.00354496 \text{ seconds} \]](https://img.qammunity.org/2021/formulas/physics/high-school/ron0mgxeoarpu0va1ua4tp2oc1fggoernq.png)
Frequency (F) is the reciprocal of the time period (T):
![\[ Frequency (F) = (1)/(T) \]](https://img.qammunity.org/2021/formulas/physics/high-school/xnx2t0k0sly20smoyzk54urg17l1iogm0o.png)
![\[ Frequency (F) = (1)/(1.00354496) \]](https://img.qammunity.org/2021/formulas/physics/high-school/f6lzewdgqi7h1mo70j36wfw5qmrfmoiyro.png)
![\[ Frequency (F) = 0.996467562 \text{ Hz} \]](https://img.qammunity.org/2021/formulas/physics/high-school/z4f2pew7k1waullhxszoibgg95pa340axv.png)
