Physics

The correct example of an unbalanced force is: A baseball that has just been thrown to home plate.

When the baseball is thrown, it experiences an unbalanced force due to the force applied by the pitcher. This force causes the ball to accelerate towards home plate, indicating that the forces acting on it are not equal and opposite.

Option A

A plate sitting on a dining table: This is an example of balanced forces, as the gravitational force is balanced by the normal force from the table.
