PHY 2130 Homework solutions Assignment 9 9.14 Let the weight of the car be W . Then, each tire supports 4 W , and the gauge pressure is 4 F W P A A = = . Thus, ( 29 ( 29 2 5 4 4 0.024 m 2.0 10  Pa W A P = = × = 4 1.9 10  N × 9.18 The needed gauge pressure is 0 gauge P P P gh ρ = - = ( 29 3 3 2 kg m 1 m 10   9.80  1200 ft m s 3.281 ft  = = 6 3.58 10  Pa × 9.19 The density of the solution is 3 3 1.02 1.02 10  kg m water = = × . The gauge pressure of the fluid at the level of the needle must equal the gauge pressure in the vein, so 4 1.33 10  Pa gauge P gh = = ×
