One day Isabella decided to take her dog Pablito on a walk. When Isabella put Pablito’s leash on his collar, Pablito immediately began pulling on the leash. When Pablito pulled, he was putting a(n) 

​ (a)  

 force on the leash. Isabella pulled back on the leash so Pablito would stay still. Isabella’s pull and Pablito’s pull were equal, so the two forces were 

​ (b)  

 . Then, Pablito pulled so hard that Isabella dropped the leash. Pablito’s pull was so hard that the forces on the leash were 

​ (c)  

 , and he was able to run away.
