Bicycle caliper brakes consist of rubber pads mounted in rigid metal "shoes." the normal force applied by a bicycle caliper brake pad to the wheel rim is about 4.00 × 10 2 n . the contact area of the brake pad is approximately 4.0 cm × 0 .70 cm , with the long dimension parallel to the rim’s rotation. the pad is 1.0 cm thick. the coefficient of kinetic friction between the rubber pad and the aluminum rim is 0.50. given that the shear modulus of the rubber is 0.30 mpa, calculate the deformation angle φ of the brake pad

How have the competing explanations' experiments on atoms affected the development of the atomic model?
