Group of answer choices

Yes

No

Question 9

What error can you expect if you use the stopwatch to measure the time for only 10 oscillations instead of 50 as mentioned in the manual?

Group of answer choices

The time period becomes smaller

Time period remains same, but the error in its measurement increases.

The time period remains same, and the error in its measurement decreases.

The time period becomes longer
