Answer 2

Cut the rubber band so it's a single strand, not a loop. Draw two lines across the band a known distance x0 apart (e.g., 10 cm). Hang a known weight on the band and measure the new distance X1 between marks. The spring constant k = (X1-X0)/(mg), where m is the mass of the weight. Note that the spring constant is that of the section of rubber band that is between the marks.
Plotting: You can plot X1-X0 on the x axis and weight mg on the y axis, and repeat for different values of m. The slope of the plot is the spring constant k.
Precaution: Don't use a huge rubber band and huge weight. It could snap and injure you or at least change your attitude.

Answer 3

Rubber bands do no longer obey Hooke’s regulation. Their resistance to extension isn't linearly proportional to their extension. The resistance of rubber to extension is likewise a functionality of ways briskly the rubber is prolonged. one thank you to diploma this (a minimum of theoretically… there could be experimental problems) is to droop a weight from a rubber band, set the burden into vertical action of a few amplitude, and diploma the era of the ensuing damped oscillation as a functionality of its amplitude. To appropriately type the fee-based action, using non-linear differential equations is needed.
