A box moves to the left at constant speed across a rough horizontal floor. A rope pulls the box with a force directed 30.0° above the horizontal toward the left, as shown. How does the magnitude of the normal force compare with the box’s weight? Draw a free-body diagram of the box.

A copper wire of diameter 1.0 mm carries 2.0 A of conventional current to the left. Assume 8.5 × 10²⁸ conduction electrons per cubic meter. What are the magnitude and direction of the electrons’ average drift velocity? Use e = 1.60 × 10⁻¹⁹ C. Show all work.
