The “mean-speed theorem” for finding average velocity under constant acceleration, proposed by the Oxford Calculators, and demonstrated geometrically by Nicole Oresme, is expressed algebraically as: density = weight/volume (m1)(v1) = (m2)(v2) (vm) = 1/2 (v0 + vf) s = (v0)(t) + 1/2 (a)(t2) velocity = distance/time

The “mean-speed theorem” for calculating average velocity under constant acceleration, developed by Thomas Bradwardine and the Mertonian Calculators at Oxford University, is expressed algebraically as: density = weight/volume (m1)(v1) = (m2)(v2) C. (vm) = 1/2 (v0 + vf) s = (v0)(t) + 1/2 (a)(t2)  velocity = distance/time

The kinetic data in the following table were obtained for the reaction of carbon dioxide and water to produce bicarbonate and hydrogen ion catalyzed by carbonic anhydrase. H2O + CO2--> HCO3 + H+ Carbon Dioxide Concentration (mmol L-') 1.25 2.5 5.0 20.0 1/Velocity (M'sec) 36 x 10³ 20 x 10³ 12 x 10³ 6 x 10³ [H. DeVoe and G. B. Kistiakowsky, J. Am. Chem. Soc. 1961 83 (2), 274-280.] Use Excel (or similar) to generate a Line Weaver-Burke plot, then use the equation for a linear-fitted trend line to calculate the substrate affinity of CO2 for carbonic anhydrase. Answer in units of mM. Enter numerical values only, no letters or symbols. Round answer to 2 significant figures.

If 46.5 mol of an ideal gas occupies 95.5 L at 373 K, what is the pressure of the gas? pressure: I atm

Calculate the relative V̇O2 of a 80 kg person cycling 80 RPM with a resistance of 10 kg, then answer the following questions: Do you think the work rate values are attainable? If your answer is “no”, give a short explanation of why you believe this. If the answer to the previous question was yes, do you believe you would attain a steady state of oxygen consumption? Explain your answer.

Based on the speculations of Nicole Oresme, and on the equation relating spatial distance, time, initial velocity, and constant acceleration developed by the Mertonian Calculators, how far would you expect a falling object to travel in 4 seconds (falling from a spaceship towards the Earth, in the vacuum of space), starting at 0 feet/second, with constant acceleration (32 feet/sec2), and neglecting possible air friction? 64 feet 144 feet 256 feet 400 feet 576 feet
