Final Answer:
1. a. Diagram A (30 N right, 5 N left) — net force = 25 N right
b. Object will move to the right because the rightward force is stronger.
2. a. Diagram A has 10 kg mass, Diagram B has 5 kg mass — mass is different.
b. Diagram B has greater acceleration because smaller mass with same force means faster movement.
3. a. Diagram A: 30 N on 3 kg → acceleration = 10 m/s²; Diagram B: 30 N on 1 kg → acceleration = 30 m/s²
b. Diagram B has greater acceleration because same force on smaller mass makes it speed up more.
4. a. Diagram A has 30 N force on 1 kg; Diagram B has 15 N force on 1 kg — force is different.
b. Diagram A has greater acceleration because more force on same mass means faster movement.
