For an answer to be complete, the units need to be specified. Why?​


A measurement must be measured against a scale, and the units provide that scale. Units must be specified or the answer is meaningless- the answer could mean a variety of quantities, and could be interpreted in a variety of ways.
Eunice must be specified so that it is clear what the number refers to. Hope this helps

so you know the units in the problem and answer are the same, if they aren't you have to convert them to the same units.


unit is necessary to communicate values of the physical quantity for example can main to someone a particular length without using some sort of unit is impossible because a length cannot be described without a reference used to make sense of the value given

Do you know the answer?
