Multiple-choice questions may continue on the next column or page – find all choices before answering. 001 10.0 points Blood of density 1590 kg / m 3 that is to be ad- ministered to a patient is raised about 1 . 29 m higher than the level of the patient’s arm. How much greater is the pressure of the blood than it would be if the container were at the same level as the arm? The acceleration of gravity is 9 . 8 m / s 2 . Answer in units of Pa. 002 (part 1 of 3) 10.0 points A column of water has a diameter of 1 . 8 m and a depth of 10 m. How much pressure is at the bottom of the column? The acceleration of gravity is 9 . 8 N / kg . Answer in units of Pa. 003 (part 2 of 3) 10.0 points What is the weight of this column of water? Answer in units of N. 004 (part 3 of 3) 10.0 points What would be the pressure if the column had a radius of 5 m and the same depth? Answer in units of Pa. 005 10.0 points The four tires of an automobile are inflated to an absolute pressure of 1 . 3 × 10 5 Pa. Each tire has an area of 0 . 02 m 2 in contact with the ground. Determine the weight of the automobile. Answer in units of N. 006 (part 1 of 2) 10.0 points The cross-sectional area of the output piston in a hydraulic device is 15 times the input piston’s area.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
