Given points A(2, 1) and B(-4, 1). Explain why the vector AB is parallel to the x-axis?

• because vector AB is a multiple of the unit vector i

• because vector AB is a multiple of the unit vector j

• because vector AB is a multiple of the unit vector k

The scalar product of u and v is zero, therefore...

• vectors u and v are parallel

• vectors u and v are perpendicular

• vectors u and v are equal

• vectors u and v are multiples

If the dot product of two vectors is equal to zero, then what do we know about the two vectors?

• They are parallel.

• They are orthogonal.

• They are neither.

What type of quantity is produced by the dot product of two vectors?

• scalar
• vector

What operation is required to find an angle between two vectors?

• Dot product between the two vectors

• Dot product between the two vectors divide the magnitude of both vectors

• Cosine inverse of dot product between the two vectors divide the magnitude of both vectors
