Give your answer to 1 decimal place. Question 12 1 pts A large box has a weight of W = 100 N and is resting on a rough surface. A horizontal force of F = 50 N is applied sideways to the box. but this does not cause the box to move. Which of the following statements about the situation is true? The force of the surface acting on the box is greater than 100 N The force of friction opposing the hour's siding at this point is less than 50 N ' The force of friction opposing the boat's sliding at this point is exactly 50 N The force of friction opposing the hour's sliding cannot be determined The force of friction opposing the lane's siding at this point is greater than 50 N Question 13 1 pls An ice skater is able to spin at 8.9 revolutions per second.
