The four tires of an automobile are inflated to a gauge pressure of 2.0 x 10° Pa. Each tire has an area of 0.022 m in contact with the ground. Determine the weight of the automobile.

A 46kg woman wearing shoes with high heels has her weight resting only on an area of 5.5 x 10-³ m² per shoe. a) How much pressure acts on the woman's feet? (both feet!) ✓ ✓ ✓ b) If the woman stood flat footed without high heeled shoes, what affect would it have on the pressure she feels on her feet? Circle one of the following: ✓ a. Increase Pressure b. Decrease Pressure c. No Change in Pressure

25,708 E 8. Water at a pressure of 4.70 atm at street level flows into an office building at a speed of 0.80 m/s through a pipe 5.00 cm in diameter. The pipes taper down to 2.00 cm in diameter by the top floor, 22.0 m above. Calculate the water pressure in such a pipe on the top floor. Pa 27 R DI C F V 96 5 T G tv 6.

An automobile weighing 1.19 x 104 N has weight equally distributed over its wheels. The weight of the car causes each tire to be slightly flattened on the bottom so that there is a surface area in contact with the road. The gauge pressure of the air in the tire is 1.90 x 105 Pa (27.55 lb/in2). Find the area of contact, assuming that the only forces on the section of tire in contact with the road are the air pressure and the normal force exerted by the surface of the road. (The answer is not 0.06263 m2)

(a) A submersible vehicle is in a lake at a depth of 26.6 m. What is the absolute pressure (in Pa) at this depth? The density of the water in the lake is 1.00 ✕ 103 kg/m3, and the air above is at a pressure of 101.3 kPa. ____Pa   (b) The submersible vehicle has a circular window with a diameter of 40.0 cm. What force (in N) is exerted by the water on the window of the vehicle at the depth from part (a)? (Enter the magnitude.) ____ N
