question:
Question: Will one large piece have more or less surface area than smaller pieces? 
 Answer: less
answer:
It would be hard to get a big chunk of chocolate to dissolve in your milk or hot water. Maybe you could make hot chocolate from some smaller pieces like chocolate chips, but it is much easier to add a powder to your milk. This is because the smaller the pieces are, the more surface area they have.


question:
Question: The cop shot the radar gun at the super fast car, which _____ the waves. 
 Answer: increased
answer:

A: As the car approaches the radar gun, the reflected microwaves get bunched up in front of the car. Therefore, the waves the receiver detects have a higher frequency than they would if they were being reflected from a stationary object. The faster the car is moving, the greater the increase in the frequency of the waves.
