Unformatted text preview: factor of mass. If the period changes any differently when the amplitude and mass are changed than when just the mass is changed, we are able to decide that the ring’s amplitude significantly affects the period. 3. When is a measurable difference between results considered insignificant? A measurable difference between results is considered insignificant if the uncertainties of the two measurements overlap. If parameters other than the independent parameter are not constant, the dependent factor will not always be constant. In the lab setting, it is extremely difficult to eliminate other parameters and it is therefore pretty common for a measurable difference between results to be considered insignificant. 4. Why is a linear fit of log(T) versus log(d) required to find the constants A and n and their uncertainties? Why not use the powerlaw fit of T versus d in Excel?...
