Question

2. what is the dot product between a unit vector along the z-axis and a vector a. 2 b. -3 c. 4 d. not enough information is given

Answer 1

The dot product between a unit vector along the z-axis and a vector cannot be calculated without the vector information.

Step-by-step explanation:

The dot product between a unit vector along the z-axis and a vector is calculated by multiplying the corresponding components of the two vectors and summing them up. In this case, since the unit vector along the z-axis is represented as (0, 0, 1) and the vector a is not given, we don't have enough information to calculate the dot product.
