Final answer:
To subtract vectors, subtract their components separately. The x-component of (E - F) is 3.0 cm.
Step-by-step explanation:
In order to subtract vectors, we need to subtract their components separately.
Given that vector E is (4.0 cm, E) and vector F is (1.0 cm, W), we can subtract their x-components and y-components separately.
The x-component of (E - F) is 4.0 cm - 1.0 cm = 3.0 cm, and the y-component remains the same.
Therefore, (E - F) = (3.0 cm, E).
