Yes, a vector which has zero magnitude is also a vector in case of two vectors travelling in opposite directions with equal magnitudes. At this case, the resultant vector has zero magnitude but it is still a vector. We call it a null vector.

If a vector A is multiplied by a real number (say n), the vector of same nature is obtained but its magnitude is n times that of A.

The Rh factor(the Rhesus factor or Rh antigen), is a protein that can be found on the surface of red blood cells. It is one of the most important blood group systems in human blood typing. The presence or absence of the Rh factor is denoted as either Rh-positive (+) or Rh-negative (-).

Fun fact: The Rh factor is named after the Rhesus monkey, in which the protein was first discovered.
