The swing completes 25 oscillations in 5 seconds So, It will complete 1 oscillation in 5/25 seconds = 0.2 secondsSo, the time period of the swing is 0.2 seconds. Hence, the right answer is Option C.

The time taken to complete one oscillation - a left swing and a right swing - is called the time period (T); it is measured in seconds.A swing takes 5 seconds to complete 25 oscillations. That means it would take 1 second to complete 25 ÷ 5 = 5 oscillations. That also means it would take 1 ÷ 5 = 0.2 seconds to complete 1 oscillation.So, the time period of the swing is 0.2 seconds. Hence, the right answer is Option C.

Ans 18:

Anoop Haridas from dpsmis doha, doha
Class : Class 8
I think this answer is wrong. It should be 0.2 seconds, according to the definition of a Time Period in oscillatory motion.

Ans 19:

Kaushik Bhattacharya from LVIS, NOIDA
Class : Class 7
The answer seems to be wrong. 5 seconds to complete 25 oscillations. That means for one oscillation it is 5/25 = 0.2 seconds. 'Period' usually means one complete oscillation that is 0.2 seconds and that is not given.
