(a) What is the equivalent capacitance of the group?
(b) Determine the charge on each capacitor.
the 4.00 ÂµF capacitor
the 8.00 ÂµF capacitor
(a) Compute the electrical energy used by a household whosemonthlyelectrical bill is $44, computed at therate of $0.07 perkWh.
(b) How long could this energy be used to burn ten 12 W lightbulbs?
(c) If this energy were used to raise a car of mass 2115 kg, towhat height would the car be raised?
A "pulse oximeter" operates by using light and a photocelltomeasure oxygen saturation in arterial blood. The transmissionoflight energy as it passes through a solution oflight-absorbingmolecules is described by the Beer-Lambert law,given below, whichgives the decrease in intensity I in terms of thedistance L thelight has traveled through a fluid with aconcentration C of thelight-absorbing molecule.
I =I010-ÎµCLorlog10(I / I0)=-ÎµCLThe quantity Îµ is called the extinctioncoefficient, andits value depends on the frequency of the light.(It has units ofm2/mol.) Assume that the extinctioncoefficient for 660nm light passing through a solution ofoxygenated hemoglobin isidentical to the coefficient for 940 nmlight passing throughdeoxygenated hemoglobin. Assume also that 940nm light has zeroabsorption (Îµ = 0) inoxygenated hemoglobin and 660 nmlight has zero absorption indeoxygenated hemoglobin. If 31% oftheenergy of the red source and 78% of theinfrared energy istransmitted through the blood, determine thefraction of hemoglobinthat is oxygenated.
Please show your work so I can understand. Thank You. Part Bisalready correct :]
