Question 49

A student wishes to determine the period of a simple pendulum.

The pendulum bob is released from a small angle so that it swings back and forth. The student has written down four instructions to find the period:

  1. Divide the total recorded time on the stopwatch by 20.
  2. Start the stopwatch as the pendulum bob passes through its lowest point.
  3. Stop the stopwatch.
  4. Count 20 complete oscillations.

What is the correct order of these instructions?

A

2→4→3→12 \rightarrow 4 \rightarrow 3 \rightarrow 12→4→3→1

B

2→3→4→12 \rightarrow 3 \rightarrow 4 \rightarrow 12→3→4→1

C

4→2→3→14 \rightarrow 2 \rightarrow 3 \rightarrow 14→2→3→1

D

1→2→3→41 \rightarrow 2 \rightarrow 3 \rightarrow 41→2→3→4
