In uniform circular motion, what is the mathematical relationship between the period $T$ and the frequency $f$?

If the period of an object in uniform circular motion doubles, what happens to its frequency? (Recall that $f=\frac{1}{T}$, where $f$ is frequency and $T$ is period.)

An AC waveform completes $30$ cycles in $\frac{1}{2}$ second. What is its frequency in hertz?

In the context of uniform circular motion, about how long does it take for Earth to complete a full rotation on its axis (i.e., what is the period $T$ of Earth's rotation)?

In uniform circular motion, how are the frequency $f$ and the period $T$ related?

For a particle undergoing uniform circular motion with frequency $f$, what is the period $T$ of its motion?

In uniform circular motion, how are the $f$ (frequency) and $T$ (period) of the motion related to each other?

In uniform circular motion, how are the period $T$ and frequency $f$ of the motion related?
