When asking a vector,do you need to answer both magnitude and direction ? or simply just magnitude?

Answer 1

Yes to the first question.

You have to do like this:
(ai+bj+ck) ___

In the ___ you put the vetorial unit. Like: meters, cubic meters, newtons, m/s, etc.

Answer 2

The neccessariy challenge for any actual quantity to be vector is that it ought to have the two magnitude .The adequate challenge is that it is going to obey the rule of thumb of vector addition .The path in electric powered modern purely indicated the path of flow of electrons.It would not persist with the rule of thumb of vector additon and it particularly is further or subtracted via the strategy of common algebra .it is reason modern isn't vector quantity.

Answer 3

It kinda depends on what you're using it for. But, in general, yes. You need both magnitude *and* direction (for polar coordinates) or the 'x,y components' (for rectangular coordinates) to fully describe a 2-dimensional vector. (And yes, higher dimensional vectors exist and are in common usage ☺)

Answer 4

for vector you need both direction and magnitude

Answer 5

both the magnitude and direction.

Answer 6

we need both magnitude and direction for a vector quantity whereas only magnitude is required for scalar quantity......

Answer 7

Both

Answer 8

Direction too.
