Determine the value of R1 to establish a quiescent or bias output voltage, VOUT, of 5 V. Assume that C is large. You may wish to use an electrolytic capacitor for C but be sure to note the correct polarity. Using the resistance you found for R1, find the small signal gain for the amplifier circuit. Compare your measured, theoretical, and SPICE simulated results. Increase the input voltage of your circuit while monitoring your output waveform. How large of output signals can be obtained without seeing excessive distortion of the output?

become equatorial, and all equatorial groups become axial. Larger substituents prefer to be in the equatorial position, and the relative amounts of each chair conformer are dependent on the degree of steric strain in the conformers. The difference in free energy between equatorial and axial methylcyclohexane is ~7.3 kJ/mol at 298 K; what is the ratio between the axial and equatorial conformational isomers?

Scenario: Most goats have smooth necks due to single-gene inheritance and being homozygous for the W^(0). Some goats have a pair of neck wattles and are homozygous for the W^(2) allele, while a few have only one wattle (W^(0)W^(2)). Use this scenario to answer the following questions: What mode of dominance is evident? a. complete b. partial How many phenotypes for wattle number are possible in goats? a. 0 b. 1 c. 3 Which scenario would only increase the amount of genetic diversity in the population for the presence of wattles? a. genetic drift b. migration c. mutation d. selection When are Mendel's rules in action with regard to wattle allele segregation in goats? a. selection b. gametogenesis c. mating d. fertilization Scenario: Most goats have smooth necks due to single-gene inheritance and being homozygous for the W^(0).
