Answer:
Explanation:
A Simple pendulum has length [tex]l[/tex], then it's frequency is given by [tex]f[/tex] = [tex]\dfrac{1}{2\pi} \sqrt{\dfrac{g}{l}}[/tex]
Frequency of a pendulum is the inverse of it's Time period. It denotes the number of cycles the pendulum completes in unit time.
For the given pendulum, length [tex]l[/tex] = [tex]0.67\text{ }m[/tex], [tex]g[/tex] = [tex]9.8\text{ }\frac{m}{s^{2}}[/tex]
[tex]f=\dfrac{1}{2\pi}\sqrt{\dfrac{9.8}{0.67}}=0.61\text{ }Hz[/tex]
∴ Frequency of Simple pendulum = 0.61 Hz
