Hint: Scalar quantities are quantities that have only magnitude (no direction). Look for terms in the list that do not have direction associated with them.

Step-by-Step Solution:

Force: Force is a vector quantity because it has both magnitude and direction. It is not a scalar.

Angular Momentum: Angular momentum is a vector quantity because it depends on both the magnitude and direction of an object's angular velocity and moment of inertia. It is not a scalar.

Work: Work is a scalar quantity. It represents the energy transferred to or from an object due to a force acting on it. It has magnitude but no direction associated with it.

Current: Current is a scalar quantity. It represents the flow of electric charge and is measured in amperes. It has magnitude but no direction.

Linear Momentum: Linear momentum is a vector quantity. It is the product of an object's mass and velocity. It has both magnitude and direction.

Electric Field: Electric field is a vector quantity. It represents the force experienced by a charged particle in an electric field and has both magnitude and direction.

Average Velocity: Average velocity is a vector quantity. It is the displacement of an object divided by the time taken, and it has both magnitude and direction.

Magnetic Moment: Magnetic moment is a vector quantity. It describes the strength and orientation of a magnetic source and has both magnitude and direction.

Relative Velocity: Relative velocity is a vector quantity. It describes the velocity of one object as observed from another and has both magnitude and direction.
