Answer:
Scalar quantity. a) 35 m
Explanation:
Scalars and vectors are the geometrical representation of a physical quantity. Some physical quantities are scalars and others are vectors.
The physical quantities that are fundamental or derived belong to either of these categories.
The basic nature of a scalar is that it is expressed only with the magnitude.
The nature of a vector is that it has a magnitude as well a definite direction.
The basic way to differentiate a physical quantity whether it is a scalar or vector is to look for direction. If it has a direction, then it is a vector quantity or else it is a scalar. It is notable that every physical quantity has a magnitude.
Hence, the scalar quantity in the given list is a). 35 m
