Depressing the brake pedal in a carpushes on a piston with cross-sectional area 3.0cm2.the
piston applies pressure to the brake fluid, which is connected totwo pistons, each with area 12.0
cm2. each of these pistonspresses a brake pad against one side of a rotor attached to one ofthe
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?

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c. what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
