(a) As blood passes through the capillary bed in an organ, the capillaries join to form venules (small veins). If the blood speed increases by a factor of 4.00 and the total cross-sectional area of the venules is 10.0 cm2, what is the total cross-sectional area of the capillaries feeding these venules? (b) How many capillaries are involved if their average diameter is 10.0 m?
Suppose you are at the top of Mount Everest and you fill a water balloon. The air pressure at the top of Mount Everest is 58 kPa. a. What is the fractional change in the balloons volume V/Vi when you take it to sea level? b. If instead you take it 100 m below the surface of the ocean, what is the fractional change in its volume?
(a) Calculate the absolute pressure at an ocean depth of 1 000 m. Assume the density of seawater is 1 030 kg/m3 and the air above exerts a pressure of 101.3 kPa. (b) At this depth, what is the buoyant force on a spherical submarine having a diameter of 5.00 m?
When a person sits erect, increasing the vertical position of their brain by 36.0 cm, the heart must continue to pump blood to the brain at the same rate.

Directions: The problem below is designed to be done as group work in class. The human ear canal has a typical length of about 2.2 cm and can be modeled as a tube open at one end and closed at the eardrum. the vocal tract, when you aren't swallowing, are membranous folds that close and open to modify the pressure at the vocal folds. b. If the vocal tract with closed vocal folds is mod- eled as a pipe closed only on one end, predict the length of the vocal tract corresponding to the fun- damental frequency for hearing just calculated in part (a). c. Calculate the fundamental frequency of the human voice if L= 17 cm. a. Calculate the fundamental frequency that humans should be expected to hear best. Assume that the speed of sound is 345 m/s in air. Looking deeply down your friend's throat, or perhaps looking at a photograph, you observe the vocal tract. Ar the bottom of

How much work is required to pump the water out of the trough (to the level at the top of the trough) when it is full? Use 1000 kg/m³ for the density of water and 9.8 m/s² for the acceleration due to gravity. b. If the length is doubled, is the required work doubled? Explain. c. If the radius is doubled, is the required work doubled? Explain. 1 m 0.3 m
Hi, please show full solutions and also explain how you get the answers in physics terms so it's understandable. The correct final answers are written beside too. This is one whole question to be answered. I can't post it separately since it's related. Thank you. 10. You push the spring of a 42 g popper toy down 3.0 cm to lock the suction cup down.
