You want to set up an experiment in which the forces attract each other. What must your set up look like?

Use two magnants with opposite poles South and north attract to each other same poles push away. So using two magnants as the forces that will attract each other.

Explanation: I feel like this is how I would go about it but If it is wrong I apologize but I don't know what else they would want. So that said Good luck :) hope this helps.

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
