Cathy has just given birth to a little girl. When the nurse tried to feed her or bather her, the baby becomes cyanotic. Physical examination indicates no structural deformities. Blood gas levels show only 60% saturation with oxygen. What may be causing this problem 16) a) The infant has malformed digestive system b) The lungs are hyperventilating c) The lungs are hypoventilating d) The cardiovascular supply of the lungs is impaired e) The infant is bom with only one lung...

The sperm whale can dive to a depth of 2250 meters. For sea water with a density of 1020 kg/m3 what is the difference in pressure at this depth as compared to the surface? Supply your answer in atmospheres" (atm), where 1 atm approximately equals 1x105 Pa. (This is an incredibly large pressure. Human bodies would be crushed. The deepest human dive recorded was around 300 m, and even then, the diver had to spend 12 hours to surface from...

Many people have imagined that if they were to float the top of a flexible snorkel tube out of the water, they would be able to breathe through it while walking underwater. However, they generally do not consider just how much water pressure opposes the expansion of the chest and the inflation of the lungs. Suppose you can barely breathe while lying on the floor with a 370 N weight on your chest. How far below the surface of the...

A large glass container has a volume of 10.0 m at a temperature of 20.0 C and is completely filed with ethanol. A crane lowers a statue made of brass into the container and when it is completely submerged, you notice that 0.10 m of ethanol has overflowed from the container. Notes: Please keep at least 4 -5 significant figures in your calculations. ßglass-: 17x 10-s 1 /K, ßethano.-75x 10-s 1/K, pbras.-62x 10-s 1/K 4) uspglass = 2270 kg/m3 ,...

PHY121 Sample Final problems: thermodynamics, heat, and fluids 10pts 1. A large chemical tank containing acid springs a leak in a seam at the bottom. The air pressure outside the tank is atmospheric(Patm 1,013 x10s N/m2) and the absolute pressure inside the tank at the top is 1.4 x 10s Pa with the hole being 2.7 m below the level of the acid in the tank. What velocity will the acid exit the tank through the hole?...

B2 The University has decided to commission a large iconic sculpture which is to be erected in place of the old library. The structure is intended to acknowledge the industrial heritage of the region whilst at the same time linking to the University's motto "Per Ardua Ad Alta" (through efforts to high things"). An (unimaginative) artist is suggesting that a large circular chimney (diameter D, height h) should be built using the bricks from the old library. Concern has been...

ECE Review Worksheet 1 AP Physics Mr. Marrash 1. A space traveler weighs 980 N on Earth. What will the traveler weight on another planet whose radius is 3 times that of the Earth and whose mass is also 9 times that of the Earth. Do not use any numerical values of the universal gravitational constant G, the mass of Earth, or the radius of Earth to get your answer. 2. Two skaters, a man and a woman, are standing...

The flight attendant had to ask her twice, “Anything to drink, ma’am?” “Oh, sorry. Water, no ice, please,” said Noelle Freeman, the CFO of Franklin Climate Systems. Watching the clouds out her window at 30,000 feet, she’d been deep in thought. She was on her way home from two days in Arkansas visiting her company’s largest facility. Franklin was in the business of designing, engineering, and manufacturing climate control systems for cars and SUVs. This is a division of FB...
