You express a vector along the X-axis as a negative vector when the arrow representing the vector would point toward negative x.
A vector can be represented in terms of its rectangular components for example : V= Ix + Jy + Kz I, J and K are the rectangular vector direction components and x, y and z are the scalar measures along the components.
cross product of tow vector result in a vector which is perpendicular the multiplying vector then these three vector are perpedicular
opposite direction.
Total force (or net force) is the vector sum of the individual forces. Huh? OK, if all forces are along the x-axis, you add the positive forces and subtract the negative forces -- force is a vector, a quantity having a size and a direction.
Quite simply, this means that momentum is a vector quantity; the direction is relevant. This is useful, for example, for calculations involving the conservation of momentum. Actually momentum is the product of velocity and mass, and velocity is also a vector quantity - thus, in this example, one object will have a positive velocity (more precisely: a positive component of the velocity along the x-axis, for example), the other, negative. Multiplying this velocity by the mass will also give a quantity which may be positive or negative (or rather, have positive or negative components).

Yes. The "direction" of the vector is along the axis of rotation.Yes. The "direction" of the vector is along the axis of rotation.Yes. The "direction" of the vector is along the axis of rotation.Yes. The "direction" of the vector is along the axis of rotation.

A tangent of the vector is the projection of a vector along the axes of a coordinate system.
Vector b would be along the z axis, it could have any magnitude.
At what angle should a vector be directed to so that its x component is equal to its y component
No. Cos theta (Cos θ) is a trigonometric function. A vector is any physical quantity which has both magnitude and direction. For example, Displacement. Displacement has a magnitude like 240m or 0 or 13 m, etc. It also depends on the direction. If an object moves along the positive direction of x-axis, then the displacement will have a positive sign and if it moves along the negative direction of x-axis, then displacement will be negative. Thus, it has both direction and magnitude and so is a vector. Cos theta is a trigonometric function, strictly speaking.
cross product of tow vector result in a vector which is perpendicular the multiplying vector then these three vector are perpedicular
The x component of V1 is -6.6 the y component of V1 is 0.
Vector A is parallel to the cross product of vectors B and C, and it is parallel to the axis that neither B or C lie along if the two other axes are defined as the axes that B and C lie along.
Their directions are perpendicular.
