Answer:
Step-by-step explanation:
Because scalars are physical quantities that are unaffected by changes to a vector space basis and because vectors require having a magnitude and a direction, one can deduce that "10m" is a measurement.
You can think of the scalar being a plain number, the vector being the direction accompanied with the scalar (giving the vector magnitude), and then the measurement are the units you apply.
"Ten feet north."
Scalar -- Ten
Vector -- North
Measurement -- Feet
