A typical "fast" pH electrode has a time constant ofone second. (If the response of the electrode to a step change in pH is modeled as a first-order response, the time constant of thefirst-order system is 1.0s) In arterial blood the primary oscillatory component of pH is due to respiration. Assume that thiscomponent is exactly sinusoidal. If the above electrode is used tomeasure the pH of arterial blood in vivo, and if the subject isbreathing at 0.5Hz, in the steady state how much will the trueamplitude of the oscillation in pH be attenuated at the output of the pH electrode?

2 single-phase AC motors connected in parallel are fed from a220 volt source. The motors have the following ratings: Motor #1: 220V, POUT = 50 hp, Efficiency = 82%, PF =0.82 lagging Motor #2: 220V, POUT = 75 hp, Efficiency = 86%, PF =0.85 lagging
The transformer is supplying a load that draws rated current at 480V and 75 percent power-factor lagging. Sketch the appropriate equivalent circuit and determine (a) the equivalent resistance and equivalent reactance referred to the high side
Write a declaration for a two-dimensional array named temperature reads. (For simplicity, assume that a month has 30 days.) The rows of the array should represent days of the month; the columns should represent hours of the day.
