d.For one of the four masses, calculate the ratio of the measured periods of the two springs (long spring divided by short spring). Calculate a theoretical value for this ratio using the spring constants (tip: refer to the equation for the period of the spring above), and calculate the percent difference. Show all your work here. e.Why have we not bothered to carefully measure the amplitude of the oscillations for any part of this experiment? Be specific -you need to give more explanation than just saying "the amplitude doesn't matter
