•The plot of cell voltage vs pH shows a negative slope. •Plots of cell voltage vs either log([Cu2+]) or log([Ag+]) have positive slopes. Explain the difference.
A V vs I curve for a diode is plotted Label the appropriate axes V and I. The plot below shows the current through the diode is 0.002 A at 0.6 V and 0.02 A and 0.7 V.Calculate the resistance at each voltage. Does the resistance of the device increase,decrease or remain the same as the voltage increases from 0.6 V to 0.7 V? Is this an ohmic or non-ohmic conductor?
What is ohmic resistance? What is nonohmic resistance? Why does the resistance increase in the nonohmic resistance as Voltage increases? What is the physical property of slope (change in V/ change in I) on the V versus I plot? Is the resistance positive or negative for most metals? Does it depend on whether the voltage is positive or negative? Explain.
Q2 please! (ii) Does the slope of your long-run total cost curve correspond to your (iii) Explain why, at any output level, the long-run total cost is always less than prediction in Part (2) or equal to the short-run total cost. Long-run marginal cost curve On Curve Sheet C, draw the long-run marginal cost curve. (7) (8) (i) (ii) Long-run average cost. On the attached Curve Sheet C, draw the long-run average cost curve. Explain why, at any output level,...
