(4 points) Two smooth disks about the size of drink coasters are identical in size and overall appearance, except that one is composed of radioactive cobalt (Co) and the other of iron (Fe), which is not radioactive. The two disks are exactly the same size; their weights are slightly different because they are made from different materials. However, no scale is available to measure the weight and you are unable to discern which one is heavier by handling them (something you must avoid since one is radioactive).However, there is an air hockey table available (i.e., an air table on which the disks can move with nearly zero friction). You have been given the task to determine which of the two disks is radioactive (a radiation detector is not available).Describe a one-dimensional collision experiment that does not require measuring the masses or speeds of the disks that uses the air hockey table to reveal which disk is heavier, and explain how it will provide the information that you seek.The densities of the materials in g/cm3 are: Fe (7.86) and Co (8.90).
