Part 1: Take the Communication Quiz

Go to  and take the communication quiz to measure your communication skills. Take a screenshot of your quiz results. Note: You will be submitting a screenshot of your quiz results along with your reflection. Part 2: Review the feedback of your quiz results and create a refection discussing your results. You will write a one to two (1-2) page paper in which you:

Summarize the results of your communication quiz by keeping the following questions in mind: What kind of communicator did you believe you were prior to taking the quiz? After taking the communication quiz, what did the results tell you about how you really communicate? Provide a conclusion that discusses lessons learned after taking the communication quiz. Next describe three (3) characteristics of an effective communicator; then, suggest two (2) ways you can improve your own communication Use correct sentence mechanics, grammar, spelling, punctuation, and style. Your assignment must follow these formatting requirements:

Be typed, double-spaced, using Times New Roman font (size 12), with 1-inch margins on all sides. Check with your professor for any additional instructions. Include a cover page containing the title of the assignment, students name, professors name, course, and date. (The cover page is not included in the required page count.)

## An operational amplifier is built using a bipolar-transistor differential input stage.

An operational amplifier is built using a bipolar-transistor differential input stage. It is found that when the inverting input of the amplifier is grounded, the output voltage of the amplifier is zero at 25° C when a positive voltage of magnitude ?V is applied to the no inverting input of the amplifier. You may assume that this offset and any temperature-dependent drift of the operational amplifier are caused only by a mismatch between the quantities Is of the input-transistor pair, and that transistor variables are related by Eqn. 7.1.

The operational amplifier is intended for use in an inverting-amplifier connection, and therefore it is possible to reduce the effective offset at the inverting input to zero at 250 C by applying a voltage ?V to the no inverting input. Three techniques for obtaining this bias voltage are indicated in Fig. 7.28. Comment on the effectiveness of these three balancing methods in reducing the temperature drift of the amplifier. Assume that the diode forward-voltage variation with temperature is given by in parts b and c.

To determine the formation constant of a 1:1 complex, the absorbances below were measured at 470 nm in a 2.50-cm cell for the ligand concentrations shown. The total metal concentration was cM = 7.50×10-4 M.

(a) Use linear regression and the Benesi-Hildebrand equation (Equation 14·11) to determine the formation constant and the difference in molar absorptivities at 470 nm.

(b) Use nonlinear regression and Equation 14-10 to find the values of Kt and ∆ε. Start with initial estimates of Kt = 50 and ∆ε= 50.

Show transcribed image text A metal alloy rod inside a furnace is subjected to a constant axial load that induces a constant axial stress in the rod of 500 psi when the furnace is operational.
