q1 electricity
resistors battery voltmeter
q2
stand stopwatch rubber band weight similar to 2012 p34 may/june
limitations
1.two readings not enough to draw conclusion
2.difficult to judge end of oscillation
3.mass tends to rotate as well as oscillate
4.period effected when rubber band extends
improvements
1.take more reading and plot a graph.
2.use video playback camera to judge end of oscillations
3.use thinner band for precision in period
4.use vernier calipers for measuring diameter more precisely
