The aorta carries blood away from the heart at a speed of about40 cm/s and has a radius of approximately 1.1 cm.
the aortabranches eventually into a large number of tiny capillaries thatdistribute the blood to the various body organs.
in a capillary, the blood speed is approximately 0.007 cm/s, and the radius isabout 6.0 10-4 cm.
treat the blood as an incompressiblefluid, and use these data to determine the approximate number ofcapillaries in the human body.

The california mussel (mytilus californianus) attaches itself to a rock or other solid surface with a bundle of filaments known as the byssus. imagine that 15.0 j of work is done to stretch the distal end of the byssus. it releases 10.8 j of thermal energy as it relaxes. what is the resilience of the distal end of the byssus?

Awelder using a tank of volume 7.50×10^-2 m^3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.30×10^5 pa and temperature of 37.1 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 23.1 ∘c, the gauge pressure of the oxygen in the tank is 2.00×10^5 pa . a) find the initial mass of oxygen. b) find the mass of oxygen that has leaked out.
