Model answer

What a good answer should say

  • 1.23 seconds

Explanation

Why this works

The correct answer is 1.23 seconds. This option is correct for Periodic motion because it applies the ideal gas reasoning idea in the stem and keeps the relevant quantity, unit, and physical conclusion together.

The alternatives either use a neighbouring formula, omit a required variable, or describe a different physical situation.
