Total time
- 4. Multiple Choice
The time taken by a simple pendulum to complete each oscillation remains ......... .
Different
Same
Both (a) and (b)
None of the above
- 5. Multiple Choice
From the images given below choose the image of a Simple pendulum.
- 6. Multiple Choice
The formula to find the total time taken by a simple pendulum is:
Total Time Taken= Speed × Distance
Total Time Taken= Time period/ No. of Oscillations
Total Time Taken= Time period × Number of oscillations

- 9. Multiple Choice
If we denote speed by S, distance by D and time by T, the relationship between these quantities is
S= D×T
S= T/D
S= D/T
