This is a rotational inertia lab. using the given data, answer:1. theoretically, how should the slopes of all subsequent trials compare to one with the platter only?2. name the primary sources of error in this experiment and state which way (too high or too low) it would tend to throw off the results for experimental "I" values obtained with this method.Explain 3) derive eqn 5 from equations 1-4.
