IV
Correct Answer
A. IIIExplanation
Diagram III represents the vector addition C = -A + B. In this diagram, vector A is shown in the opposite direction with a negative sign, and vector B is shown in the same direction. When we subtract vector A from vector B, we get vector C. Therefore, diagram III is the correct representation of the vector addition C = -A + B.Rate this question:

IV
Correct Answer
A. IIExplanation
Diagram II represents the vector addition C = A + B because it shows the two vectors A and B being added head-to-tail. The resulting vector C starts at the tail of A and ends at the head of B. This is the correct method of vector addition, where the magnitudes and directions of A and B are combined to determine the magnitude and direction of C.Rate this question:

IV
Correct Answer
A. IVExplanation
Diagram IV represents the vector addition C = A - B. In this diagram, vector B is subtracted from vector A, resulting in vector C. The direction of vector C is determined by subtracting the direction of vector B from the direction of vector A. The magnitude of vector C is determined by subtracting the magnitude of vector B from the magnitude of vector A. Therefore, diagram IV correctly represents the vector addition C = A - B.Rate this question:

IV
Correct Answer
A. IVExplanation
Diagram IV represents the vector addition C = A - B because it shows the vector A pointing in one direction and the vector B pointing in the opposite direction. When we subtract vector B from vector A, we get vector C which is shown in Diagram IV. The other diagrams do not accurately represent the subtraction of vector B from vector A.Rate this question:
