A student investigates the oscillation of a mass suspended from a spring.
The student pulls the mass down from its rest position P and then releases it so that it oscillates vertically.
The student then follows the instructions listed to find the period of the oscillating mass.
1. Count 10 complete oscillations.
2. Divide the time on the stop-watch by 10.
3. Start the stop-watch as the mass passes upwards through point P.
4. Stop the stop-watch.
What is the correct order of these instructions?
