Depressing the brake pedal in a carpushes on a piston with cross-sectional area 3.0cm2.thepiston applies pressure to the brake fluid, which is connected totwo pistons, each with area 12.0cm2. each of these pistonspresses a brake pad against one side of a rotor attached to one of the rotating wheels (the figure below )when the force applied by the brake pedal to thesmall piston is 7.5 n, what is the normalforce applied to each side of the rotor? (b) if the coefficientof kinetic friction between a brake pad andthe rotor is 0.80 and each pad is (on average) 12 cmfrom the rotation axis of the rotor, what isthe torque on the rotor due to the two pads?

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)
