7th answer and meaning of the question

Answer 1

4) False statement is:-

(b) Time is a vector quantity which has direction always in forward direction.

because the time has an origin From then it continuous in foreward only.

( The origin is big bang theory)

Also time has magnitude but then also it's not any vector quantity because the time does not have all the properties of vector quantity.

There is something lacking in the concept of time as a vector.

5)

(a) Newton /meter

because the every vector quantity must include meter as it's unit.

6)

(d) A vectro is not changed if it slids parallal to itself

But when a vector is roated itself then the direction also changes then the vectro also get changed.

7)

(c) Scalar + vectro is correct .
