a pendelum makes 33 complete back-and-forth cycles of vibration in 11 seconds, what is its frequency and period of the pendelum?
You need to use th equation that relates period, time and cycle, such that:
Period `= t/c`
t represents the time needed for something to happen
c represents the number of cycles
Since the problem provides that inofrmation that pendulum makes 33 complete cycles of vibrations in 11 seconds, yields:
Period `= 11/33 = 0.33` seconds
Using the standard symbols for period and frequency yields:
`T = 1/f => f = 1/T => f = 1/0.33 ~~ 3.03`
Hence, evaluating the period and frequency of pendulum, under the given conditions, yields `T = 0.33` seconds and `f ~~ 3.03` Hz.
