X A 1m tall cylinder is filled with half water and half oil. What is the total pressure (in Pa) at the base of the cylinder? Density of water is 1000 kg/m^3 and density of oil is 900 kg/m^3. * 40,000 5,000 9,000 9,500 Correct answer

Assume that the left side of your heart creates a pressure of 121 mm Hg by exerting a force directly on the blood over an effective area of 16.0 cm2. What force (in N) does it exert to accomplish this? N

1. Suppose a person is 182 cm tall. A typical blood pressure is often given as 110/70 mm Hg, with a mean pressure of 80 mm Hg. A. Do you think this is the gauge pressure or absolute pressure? Why? If the pressure at the top of the head is about 39 mm Hg, how far away is this person's head from the heart? Assume the density of blood is about 6% higher than that of water. t, What then would be the blood pressure.of this 6, person at their feet? b. Suppose this person suffers a puncture wound around the same height as the heart where the opening is about 3 mm in diameter. How far could blood shoot from their body assuming it comes out horizontally with 0 m/s initial horizontal velocity? %3D = 0.754 Since horizontal velocity is zero it will not go eny for than body Please explain the variábles used in the equation to solve for F= P.A in partad of this question.

9. A liquid is flowing through a horizontal pipe whose radius is 2.18 x 10-2 m. The pipe bends straight upward through a height of 10.6 m and joins another horizontal pipe whose radius is 4.36 x 10-2 m. What is the speed of the liquid in the lower horizontal pipe if the pressure in both horizontal pipes is the same? m/s MAR 27 888 5 T G 6 B tv MacBook Air H 8 N 8 DIE A F10 zoom oup by mi 04 M vauies or the puffer Am

A group of acrobats form a human tower, each standing on the shoulders of another acrobat. The acrobats have mass 62.9 kg, 77.9 kg, 67.3 kg, and 53.7 kg. The most massive acrobat is on the bottom. The bottom acrobat's shoes have a total surface area of 0.0011 m2 on their soles. What is the pressure (in n/m? exerted by the bottom acrobat on the floor?

You are trying to lift a car to change a tire using a hydraulic jack.  You apply a force of 57 N to the input piston who's diameter is d1.  As a result, the output piston, which has a diameter d2, applies a force to the car. The ratio d2/d1 has a value of 7.2. Ignore the height difference between the input piston and output piston and determine the force that the output piston applies to the car.

A person who weighs 556 N is riding a 87-N mountain bike. Suppose the entire weight of the rider plus bike is supported equally by the two tires. If the gauge pressure in each tire is 6.80 x 105 Pa, what is the area of contact between each tire and the ground? Number i Units ←

3 A tall cylinder whose height is h=14.8 cm is 3. initially filled with water (1.00 g/cm) up to h=5.71 cm. Oil (0.713 g/cm) is then poured into the cylinder up to the brim of the cylinder. What is the absolute pressure at the bottom of the cylinder? Oil hc Water hw ↓ 102894 Pa 1594 Pa 1195 Pa 102495 Pa

Water pressurized to 6.5 × 10° Pa is flowing at 5.0 m/s in a pipe which contracts to 1/3 its former area. What is the pressure and velocity of the water after the contraction? Select one: O A. 2.5 x 10° Pa, 15.0 m/s O B. 4.5 × 10 Pa, 1.5 m/s O C. 3.0 × 10° Pa, 10 m/s O D. 3.0 × 10° Pa, 15.0 m/s O E. 5.5 × 10° Pa, 15.0 m/s
