Answer : 3. "It's time period is 10 s and frequency is 03 Hz. "
Explanation :
We can do this by dividing the number of oscillations (30) by the total time taken (3 seconds): Frequency = 30 oscillations / 3 seconds = 10 Hz Therefore, the correct statement is B. Its time period is 0.1 s and frequency is 10 Hz
