When emma pushes a bag with a force of 27 newtons, the coefficient of kinetic friction between the bag and the floor is 0.23. what is the normal force acting on the bag by the floor? . a. 0.085 newtons b. 27 newtons c. 2.7 × 10^2 newtons . d. 1.2 × 10^2 newtons

The normal force acting on the bag by the floor is calculated using th data on the force used to push the bag and the coefficient of friction between the bag and the floor. The normal force is determined through the formula Force / kin.coeff. Substituting, 27 N / 0.23 is equal to 117. 39 N. The answer is D.
