If the period of a wave is 0.05 s, then what is its frequency?

20

Solution:

We Know that frequenency is defined as the number of times something happens within a specific period of time.

Frequency is related with time by following formula

Frequency=

Here T is time period=.05

Therefore,

Frequency=

Frequency=20

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
