In the context of vectors, which of the following are correct?
The magnitude of a vector is always a scalar quantity.
A scalar multiplies only the x-component of a vector.
Vector addition can be visualized using the parallelogram rule.
A translation moves every point on an object the same distance, in the same direction.
