No, density is not a vector quantity. It is a scalar quantity that represents the mass of a substance per unit volume.
Density is a scalar quantity. We don't talk about the density of a material as having direction, which is a characteristic of a vector quantity.
A vector quantity.
Current density is a vector quantity because it has both magnitude and direction. It represents the flow of electric charge per unit area in a specific direction, as opposed to current which is the total amount of charge flowing through a conductor. The direction of current density indicates the direction in which the charges are moving.
It isn't, because a mass can only be positive - there are no negative masses. Also mass is only referring to one thing and this doesn't give as much information as a vector quantity. Mass is scalar.
Velocity is a vector quantity.

no, it's a vector dude
A magnetic field is neither: it is a vector field with both direction and quantity.

displacement is a vector quantity
Current is not scalar. Current is a vector quantity. For simplicity, in electric circuits, current is scalar because the direction is assumed to be one way or another, rather than three dimensional.
yes, momentum is a vector quantity.
Velocity is a vector quantity.
True. A vector quantity has both magnitude and direction, while a scalar quantity only has magnitude.
