True.

Answer:
The velocity of a falling object
Explanation:
The positive X axis is towards right and positive Y axis is towards up, so North direction is positive
A vector with less than 1 magnitude is not negative, because its magnitude may be in between 0 and 1 which is positive vector.
Any vector whose magnitude is greater than 1 is never be a negative vector.
The velocity of a falling object is towards bottom, that is towards negative Y axis. So that vector is negative.
Scientific Method: Because, they use their method which the scientific one to solve investigations.
Since they are made of different chemical make ups, boiling point and density they will most likely be in different groups on the periodic table.
