In an Archimides experiment, a group of students managed to take the following data on the mass of various aluminum cylinders in air, water, and alcohol. With the following data, answer the following table: Cylinder (Al) Length (cm) Diameter Air Water (gr) Alcohol (gr) (cm) (gr) 1.3 1.88 9.82 6.36 6.83 2 2.63 1.87 19.68 12.59 13.47 3.83 1.87 28.98 18.43 19.73 5.09 1.88 38.47 24.4 26.15 5 7.83 1.92 64.28 41.99 43.27 Cylinder (Al) % of mistake Specific density of solid (water) Theoretical solid (water) specific density 2 3 Cylinder (Al) Specific density of solid (alcohol) Theoretical solid % of mistake (alcohol) specific density 2 3 4

In 1923, the United States Army (there was no United States Air Force at that time) set a record for in-flight refueling of airplanes. Using two refueling planes, an Airco DH-4B biplane was able to remain in flight for 35 h. During the flight, the refueling planes were able to air-transfer a total of 687 gallons of fuel to the plane in 9 refueling transfers. Assume that the refueling nozzle had a diameter of 1.65 in and each refueling took 2.43 min to perform. Calculate the velocity of the fuel through the nozzle. Assume that the fuel filled the entire cross-sectional area of the nozzle. velocity: 12.94 m/s Incorrect

The systolic pressure of a patient is 110 mmHg and the diastolic pressure is 60 mmHg. Given that 760 mmHg is equivalent to 101.3 kPa, what is the systolic and diastolic blood pressure of this patient in units of Pascals?

Balloon angioplasty is a technique to restore blood flow through coronary arteries that have been narrowed by the build-up of plaque. The surgeon threads a catheter into the coronary artery, then inflates a balloon that compresses the plaque against the wall of the artery. Suppose a diseased coronary artery has a diameter of 2.0 mm. To what diameter must it be expanded to increase the blood flow by a factor of 5.0 with no change in pressure?

Assume that a raindrop has a volume of 0.05 cm^3 and you need an Avogadro's number of raindrops to fill up the cubic water tank. What is the length of the edge of the tank?

A cylinder is completely filled with water. The top of the cylinder is sealed with a tight-fitting lid. If you push down on the lid with a pressure 1000 Pa, the water pressure at the bottom of the cylinder increases by 1000 Pa increases by an amount determined by the height of the cylinder Increases by more than 1000 Pa Increases by less than 1000 Pa

Answer for a) is 1.06 x 10^6 J The answer for b) is 4.43 x 10^6 J

A wooden log is found to float in a freshwater lake. If 27% of the log's volume is above the surface, what is the log's density?
