46kg woman wearing shoes with high heels has her weight resting only on an area of 5.5 x 10³ m² ) How much pressure acts on the woman's feet? (both feet!) ✓✓✓ per shoe. ) 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

6- The maximum blood pressure in the upper arm of a healthy person is about 120 mmHg. If a vertical tube open to the atmosphere is connected to the vein in the arm of the person, determine how high the blood will rise in the tube. Take the density of the blood to be 1040 kg/m³. FO R W HZQ KC V

3. In scuba diving, a regulator is used so that the pressure of the air the diver breathes is close to that of the ambient water. A reckless swimmer decides to use a hose sticking out of the surface to breathe underwater while diving in a lake. When the air pressure in the lungs is at a pressure of around 0.155 atmospheres below the ambient pressure, lung injury may occur. Find the depth at which the swimmer would experience such a pressure differential.

Consider the pressure on a shot putter's hand as he throws the heavy shot. Area of contact= 48.5cm^2 force= 795N P= 163900 What is the ratio of this pressure to the atmostpheric pressure?  P/P0?

How to calculate:  Consider three poles with circular cross sections.  There cross sectional radii (r) and masses (m) described below.  Which one exerts largest pressure on the ground if poles stand on their circular edges. Which one exerts the least pressure?   a. Pole 1: r=2.25 cm, m=200 kg b. Pole 2: r=2.75 cm, m=250 kg c. Pole 3: r=3.25 cm, m=300 kg Given that area of a circle is r^2 where r is the radius.

1. Margaret put the 2.0 Kg brick has the dimensions 7.5 cm x 15 cm x 30 cm in the table top. Find the pressure exerted by the brick on a table when it is resting on irs face with a dimension 7.5 cm x 15 cm. Please include illustration.

23. A Boeing 737 airliner has a mass of 20 000 kg and the total area of both wings (top or bottom) is 100 m². What is the pressure difference between the top and bottom surface of each wing when the airplane is in flight at a constant altitude? a. 1960 N/m² b. C. 3 920 N/m² 7 840 N/m²

A barrel contains a 0.180 m layer of olive oil floating on water that is 0.40 m deep. If the specific gravity of the olive oil is 0.916, what is the gauge pressure at the bottom of the barrel? Use acceleration due to gravity = 9.8 m/s2. O A. 5678.6 Pa O B. 3825.9 Pa O C. 5535.82 Pa O D. 3928.9 Pa

You can chew through very tough objects with your incisors because they exert a large force on the small area of a pointed tooth. What pressure in Pa can you create by exerting a force of 470 N with your tooth on an area of 1.20 mm2? Pa
