An operational amplifier has to be designed for an on-chip audio band pass IGMF filter. Explain using appropriate mathematical derivations what the impact of reducing the input impedance (Zin), and reducing the open loop gain (A) of the opamp will have for the general opamps performance. What effect would any changes to (Zin) or (A) have on the design of an IGMF band pass filter? (true or false?) to find the book value per share of common stock, divide the company's book value by the number of outstanding common stock shares. bryce is a strong believer in actions to go along with inner thoughts. he not only thinks about caring for family members, he also drives an hour each way to visit and bring his home-bound grandparents groceries every saturday. in addition to jen, bryce is also demonstrating the confucian principle of suppose that the firm's only variable input is labor. when 50 workers are used, the average product of labor is 50 and the marginal product of labor is 75. the wage rate is $80 and the total cost of the fixed input is $500.what is the marginal cost? 8. Write and execute a query that will delete all countries that are not assigned to an office or a client. You must do this in a single query to receive credit for this question. Write the delete query below and then execute the following statement in SQL Server: Select * from Countries.

The piston is slowly moved to compress the gas to 8.80bar. (a) Considering the system to be the gas in the cylinder and neglecting Ep, write and simplify the closed-system energy balance. Do not assume that the process is isothermal in this part. (b) Suppose now that the process is carried out isothermally, and the compression work done on the gas equals 7.65L bar. If the gas is ideal so that ^ U is a function only of T, how much heat (in joules) is transferred to or from (state which) thes urroundings? (Use the gas-constant table in the back of the book to determine the factor needed to convert Lbar to joules.)(c) Suppose instead that the process is adiabatic and that ^ U increases as T increases. Is the nal system temperature greater than, equal to, or less than 30C? (Briey state your reasoning.) for controls to be effective, all operating units of an ic must provide headquarters with timely, accurate, and complete reports, including those dealing with financial, technological, market opportunity, and political and economic information. question 13 options: true false 7. write and execute a query that will remove the contract type ""time and materials"" from the contracttypes table. A corporation issued $150,000 of 10-year bonds at the stated rate of 8%, with interest payable semiannually.

The chamber temperature cannot exceed 3[C] and the temperature difference at the evaporator inlet is estimated at 7[C].You have a large flow of well water at 15[C] that you plan to use as condensing agent. The refrigerant fluid used is R-134a.For the operation of this installation, an alternative compressor was acquired. of 2,250 [cm] of displacement, which sucks steam with a superheat in the 10[C] suction pipe. This compressor rotates at 850[r.p.m.] and its volumetric efficiency is 0.8 for a compression ratio of 3.3.Calculate the degree of subcooling of the condensed fluid so that it canoperate the installation with this compressor and if it is possible to carry it out.Note: Consider a maximum admissible jump in the well water of 5[C] and a minimum temperature jump in the condenser (between refrigerant fluid and waterof well) of 5[C]. The Card Company strives to recover, reuse, and recycle paper at the end of its life cycle to be used in the production of all new greeting cards.

The bonds mature in two years and pay interest quarterly every March 31, June 30, September 30 , and December 31. All of the bonds were sold on January 1 of this year. Serotta uses the effective-interest amortization method and does not use a premium account. Assume an annual market rate of interest of 8 percent.Required:(a) Provide the journal entry to record the issuance of the bonds. The solar sunspot activity is related to solar luminosity. Showthat we expect a maximum temperature change at the earth's surfaceof around 0.2C due to a change in solar activity.
