Which of the following statements is INCORRECT?Overpotential is difference between the actual potential and the theoretical Nernst potential.O Overpotential can be considered as the additional voltage needed to achieve a desired current density beyond theequilibrium potential○ The overpotential is likely significant when the electrode reaction involves a high activation energy barrier.○ Polarization is primarily due to the voltage drop caused by the resistance of the cell components.

Let's analyze each statement to determine which one is incorrect:a. Overpotential is the difference…

3 Charged Closed Wire Consider a thin closed wire with the radius R localized at the origin on the xy-plane, which is charged uniformly with the total charge Q. (i) What is the charge density p in this problem? (ii) Calculate the electric field along the z axis? (Hint: First, consider an infinitessimal piece of the charge.)
1. Imagine a triple-slit "grating", where the distance to the screen is much larger than the distance between the slits. By using phasors, show that the intensity of the interference pattern is given by I = I(1 + 4 cos & + 4 cos² ø). (Hint: Recall the intensity of fringe pattern in Young's two-slit interference experiment.)

Why do we enter PV and FV as a negative when calculating TVM problems?
What are the two shortcomings of the direct write-off method?
5. Consider a coaxial cable which is an (infinitely) long wire of radius a, with given current flowing uniformly up it (so J(t) = I(t)/лa² goes uniformly through the wire). At the outside edge (r=a), there is an infinitesimally thin insulator, and just outside that, an infinitesimally thin sheath that returns all the current, basically a surface current going down the opposite direction carrying a total -I(t) back down. Figure out the B field everywhere in space (direction and magnitude) in terms of givens, and then find the self-inductance per length of this cable. Assume I(t) changes slowly in time, so we can use our usual quasi-static ideas. There are several ways to proceed. You might start from =LI, but this turns out to be tricky here, since the current is not confined to a single path! It is best to think about the total magnetic energy, W, stored by the magnetic field, and use our usual relation between energy and current: WL I²/2.
How does it compare with the NPV based on the WACC method? (Select the best choice below.) A. The NPV computed using the FTE method cannot be compared to the NPV based on the WACC method. B. The NPV computed using the FTE method is always higher than the NPV based on the WACC method. C. The NPV computed using the FTE method is always lower than the NPV based on the WACC method. D. The NPV computed using the FTE method is the same as the NPV based on the WACC method.
This is a multiple answer question. Section 7.2 Select all correct statements regarding covalent compounds. Covalent compounds tend to be much softer than ionic compounds. Covalent compounds are excellent conductors of electricity when dissolved in water. Covalent compounds do not exist as liquids or gases at room temperature. Covalent compounds generally display low melting points and low boiling points compared to ionic compounds. Covalent compounds are poor conductors of electricity in any state.
A particle moves along line segments from the origin to the points (2, 0, 0), (2, 5, 1), (0, 5, 1), and back to the origin under the influence of the force field F(x, y, z) = z2i+ 3xyj + 3y2k. Use Stokes' Theorem to find the work done.
