​

Answer 1

Answer:

if the two vectors are parallel, their for product is one (1).

Answer 2

Answer:

Explanation:

Dot product of two vectors is the scalar product of its magnitude multiplied with the cosine of the anhle between them.

For two parallel vectots, the angle between them is 0 and cos 0° is 1.

For eg. if 4i.5i= (4x5)xcos 0°= 20x1= 20
