A group of students estimated the spring constant, k, of a spring using the model where T is the period of oscillation of amass m attached to a spring. They

report the result as k = 9.86 [units] +/- 0.4 [units], where "units" is the appropriate unit for k.What would be an appropriate comment after examining the expression of the result? O The uncertainty is to small compared to the average value O The uncertainty is too big compared to the average value O The average value is not rounded correctly O The uncertainty is not rounded correctly. k=\frac{4 \pi^{2} m}{T^{2}}
