Question

Which natural phenomenon is the best example of periodic behavior?

A. The amount of pollution in Los Angeles as a function of time
B. The number of fish in a pond as a function of time
C. The closing value of the stock market at the end of each day
D. The number of hours of daylight each day

Answer 1

Option D is right.

Explanation:

We have chosen option D because periodic behaviour means there will be oscillation between maximum and minimum and the range will be within two values.

A is wrong since amount of pollution in Los Angels is continuously increasing and hence not periodic

B. Fish in a pond may increase continuously not periodic.

C. Closing value of stock may fluctuate but no limits for max or minimum

Hence only option D is right.

Answer 2

"The number of hours of daylight each day" is the one natural phenomenon among the choices given in the question that is the best example of periodic behavior. The correct option among all the options that are given in the question is the fourth option or option "D". I hope that the answer has come to your help.
