Question

if the time period of a body is 10 seconds what will be the frequency​

Answer 1

Answer:

If the time period of a simple pendulam is 10 seconds, then its frequency ius ______Hz.

Answer 2

$\huge\fbox\red{❥answer}$

The period of a pendulum is going to be given in units of

$\huge \frac {Some Time Interval}{Cycle}$

The frequency of a pendulum is going to be

$\huge \frac {Cycles}{Time Unit}$

Just inspecting the expected units of each, we see that frequency is simply the inverse of the period.

$Frequency= \frac \pink {1} \pink{Period}$

$Frequency= \frac \blue{1} \blue{10\frac {seconds}{cycle}}$

$Frequency= \frac \red {1} \red{10} \frac \red{cycles}\red{second}$

$Frequency=$ $\green {0.1} \frac \green{cycles}\green{second}$

$Frequency= \orange{6} \frac \orange{cycles}\orange{minute}$

Notice how, in the last step, I multiplied the fraction by 60 seconds per minute to get the magnitude of the answer above one. This step, changing the time unit to assure a frequency of at least one, is a style choice that I follow
