5. If you push the cupboards to the right, cupboard A will topple or fall faster.

6. One of the factors that makes cupboard B more stable is its shape.The shape of cupboard B gives it a bigger base area.
7. Apart from the base area, the height of an object also affects its stability.

9. The stability of an object is affected by its base area and height.
