A vector has magnitude and direction. Does it have a location in space? Can it vary with time? Will two equal vectors 'a' and 'b' at different locations in space necessarily have identical physical effects? Give examples in support of your answer.

Hii dear,
# Answers-
I'll answer all questions 1 by 1,
a) Yes/No.
Only position vectors have specific location in space. Directional vectors don't have specific location and are unaffected by location provided it's magnitude and direction remain same.
b) Yes.
Vectors do vary with time. For example, velocity is change in displacement wrt time.
c) No.
Two equal vectors having different locations don't produce the same effect. For example, two equal forces acting on different points of wheel produces torque.
Hope that is useful...
