At 37°c and atmospheric pressure the maximum volume of oxygen which blood can carry when fully oxygenated is 20 ml of o2 per 100 ml blood. cm a) how many moles of o, are carried by a liter of blood? b) hemoglobin is the oxygen transport protein in blood and has four sites for binding o2. how many thare neded to transport o, in1 hemoglobin molecules are needed to transport o2 in 1.0 l of oxygenated blood?

Apositive charge moves in the direction of an electric field. which of the following statements are true? check all that apply. check all that apply. 1.the potential energy associated with the charge decreases. 2. the electric field does positive work on the charge. 3. the electric field does negative work on the charge. 4. the potential energy associated with the charge increases. 5. the electric field does not do any work on the charge. 6. the amount of work done on the charge cannot be determined without additional information.

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
