Vector operations: Please i can not know whether each statement is true or false.
Vector operations: so I need help to know when one is true or false.
The x-component of a vector can be (+),(-), or zero
A × C = C × A
The scalar (or dot) product of two vectors can be (+),(-), or zero
If A is perpendicular to B, then B • A = 0
The magnitude of a vector is always positive or zero.
If A = B × C and C = 16j, then Ay =0
thanks,

I just want to tell you that in my physics course which is 8 points, I got 99/100, and I want to thank you, for letting me think , and because you never just gave me the answers .
I really worked hard for that score. Thanks.
I will try again and then submit my answer
