Using real world examples, compare and contrast the the characteristics of a perfect competitive firm, when a perfect competition firm produces v. shut down, stays in business v. go out of business, and the relationship between economic profit, normal profit, and accounting profit in these decisions. Use comprehensive definitions, real world examples, and comprehensive applications in your answer.

Consider the titration of 50.0 mL of 0.0500 M Cu+ with 0.1000 M Fe3+ to give Cu2+ and Fe2+ using Pt and standard H+/H2 reference electrode to find the end point. The standard electrode potentials are E0Cu+/Cu2+=0.161 V and E0Fe2+/Fe3+=0.767 V. Calculate the actual electrode potential, E, at the following volumes of Cu2+ (i) 15, (ii) 25, and (iii) 26 mL

We can use breadth-first search to find the length of longest simple path in the BFS tree
starting at s by the simple method of checking each v.d value at the end of the algorithm. BFS is
Θ(|V | + |E| and this adds only Θ(|V |) work.
Find an even easier approach that adds only constant time (Θ(1)) work via a simple modification to
the BFS algorithm.

Two financial assets with gross return (R1, R2) are jointly normally distributed. E(R1) = 1.06 and E(R2) = 1.12. V ar(R1) = 0.03, V ar(R2) = 0.04, and Cov(R1, R2) = 0.025. Draw the mean-variance frontier formed by the two assets. Mark the minimum variance. Notice that the mean of portfolio formed by these two assets falls in the interval of [1.06, 1.12].

n 2016, Gerald loaned Main Street Bakery $55,000. In 2017, he learned that he would probably receive only $6,400 of the loan. In 2018, Gerald received $3,000 in final settlement of the loan. Calculate Gerald’s possible deductions with respect to the loan for 2016, 2017, and 2018.

Part A

Find the energy U0 stored in the capacitor. Express your answer in terms of A, d, V, and ϵ0. Remember to enter ϵ0 as epsilon0.

Part B

The capacitor is now disconnected from the battery, and the plates of the capacitor are then slowly pulled apart until the separation reaches 3d. Find the new energy U1 of the capacitor after this process.

Express your answer in terms of A, d, V, and ϵ0.

Part C

The capacitor is now reconnected to the battery, and the plate separation is restored to d. A dielectric plate is slowly moved into the capacitor until the entire space between the plates is filled. Find the energy U2 of the dielectric-filled capacitor. The capacitor remains connected to the battery. The dielectric constant is K.

Express your answer in terms of A, d, V, K, and ϵ0.

A 580-mm long tungsten wire, with a 0.046-mm-diameter circular cross section, is wrapped around in the shape of a coil and used as a filament in an incandescent light bulb.
