2. Look at the data table and graph for the 50-coil electromagnet. With the 1.5 V battery, the electromagnet picked up an average of 13 paper clips, while the 25-coil electromagnet picked up an average of 6 paper clips.

a. What is the ratio of the number of turns of the 50-turn electromagnet to the number of turns of the 25-coil electromagnet?

b. What is the approximate ratio of the number of paper clips picked up by the 50-coil electromagnet?
