What is the relationship between area and length in terms of derived quantities?

• Area decreases as length increases.

• Length is the only factor determining area.

• Area is independent of length and width.

• Area is proportional to length when width is constant.

What is the SI unit for measuring force?

Explain the difference between scalar and vector quantities.

• Scalar quantities can be represented as arrows; vector quantities cannot.

• Scalar quantities have only magnitude; vector quantities have both magnitude and direction.

• Scalar quantities have direction; vector quantities have only magnitude.

• Both scalar and vector quantities have only magnitude.

How do you convert kilometers to meters?
