Question #cae9a

Answer 1

Period `T = (2 pi) /omega`

Explanation:

Period `T = (2 pi) /omega`, where `omega` is angular speed

this is a direct analogue to the linear idea that

`"time" = "Distance"/"Speed"`

.....because `2pi` is a full revolution, the "distance", and it is done at angular speed `omega`.
