    1. The problem statement, all variables and given/known data

    The dot product for two.parralel pointing.unit.vectors is ?
    A. 1
    B. 0
    C. -1
    D. Undefined


    2. Relevant equation

    3. The attempt at a solutionsince they are unit vectors they have a magnitude of 1,this implies that the dot product is 1,since the angle between them.is equal to zero and cos zero is 1,
