According to a mathematical model,the spring constant k, of a spring can be written as: k=\frac{4 \pi^{2} m}{T^{2}} where T is the period of oscillation of amass m attached to a spring.You want to estimate the value of k with minimum uncertainty possible without making graphs. What would be the main step in your method to get the desired result? O Time the period of one oscillation of the mass and use it to calculate k. O Time the period of one oscillation of several masses and calculate k for each O Time the period of many oscillations of a mass to find one average period and use it to find k. Then repeat several times to find an average k. O All methods listed above would produce the same result.
