Look at the data table and graph for the 25-coil electromagnet. With the 1.5 V battery, the
electromagnet picked up an average of 6 paper clips, and with the 6.0 V battery, it picked up
an average of 23 paper clips.
a. About how many times stronger than the 1.5 V battery is the 6.0 V battery?
b. What is the approximate ratio of the number of paper clips picked up using the 6.0 V
battery to the number picked up using the 1.5 V battery?
c. Is this a direct relationship or an indirect relationship?
