AHMAD, ASHNA 5 of 35 1 4. 6. 7 A student has two rubber balls of different masses to perform an experiment. Which experiment can the student do to objects? O Roll the rubber balls on thick carpet, and observe if either ball produces a spark. O Move a magnet near each rubber ball, and observe if either ball is attracted to the magnet. O Place the rubber balls ona rough surface, apply a small push, and record the time for each ball to move 30 cm. O Drop the rubber balls at the same time from 5 m, and record the time for each ball to hit the ground. P Type here to search 5.
