Quizplus · Accepted Answer

All the factors mentioned in options A, B, and C contribute to the amount of friction between two blocks sliding against each other. The more the blocks are pressed together, the greater the friction. The stickiness of atoms on their surfaces plays a significant role in the amount of friction that occurs when two blocks slide against each other. The kind of material being pressed will also determine the amount of friction. Hence, all the options are correct, and the answer is D.
