Answer:
The ball with mass twice as much as ball B, that is Ball A has the greater density.
The two balls have the same density.
The ball which is twice as large as ball Q, that is Ball P has the greater density.
The two balls might have the same density.
Explanation:
Ball A has greater density because the mass of an object is directly proportional to the density, i.e as the mass increases, the density also increases.
The two balls C and D have the same density. The logic is simply that the density is inversely proportional to the volume of the object but directly proportional to the mass of the object.
The ball with the large size is considered to be denser because denser objects are perceived to be denser.
