Grading for Numeric Answers Tolerance Some numeric answers to questions need to be exact. For example, the answer to the question "How many days are in a week?" must be exactly 7. In general though, numeric answers are graded as correct if they fall within an acceptable range (or tolerance) of the official correct answer. For example, if the answer to a numeric problem with a tolerance of 2% was 105, then entering any value between approximately 103 and 107 would be graded as correct, as shown in the region shaded green below. The typical grading tolerance in Mastering is 2-3%, although this value may vary (e.g. more lenient) depending on the particular problem. A number line is marked at 100, 105, and 110, where 105 is the properly-rounded answer. A green shaded region extends beyond 105 by 2 percent of this value in each direction. Significant Figures While Mastering does not directly grade your answer based on the number of significant figures it contains, the tolerance mentioned above is centered around the properly-rounded answer (as opposed to the full-precision answer). In some problems you will be explicitly told how many significant figures your answer should contain. You may find that entering extra significant figures than required often causes your answer to still fall within the accepted tolerance and thus graded as correct. However, there are problems where not rounding properly may cause your answer to fall outside the accepted tolerance, so it's important to follow the general rules for significant figures, as the following example illustrates. Suppose you are asked to find the area of a rectangle that is 3.1 cm wide and 4.4 cm long. The full-precision answer from your calculator would be 13.64 cm2, although given the rules for significant figures, this answer should be rounded to two significant figures before being entered, or 14 cm2. If you were to enter 13.64 cm2, it would not be graded as correct since this value falls outside the 2% tolerance of the properly-rounded answer of 14 cm2. Instead, you would receive feedback from Mastering telling you to check the rounding of your final answer, although you would not be deducted any points. Part A What is the area of a rectangle that is 3.1 cm wide and 4.4 cm long? Enter the full-precision answer first to see the corresponding feedback before entering the properly-rounded answer. (You do not need to enter the units in this case since they are provided to the right of the answer box). Part B Calculate the volume of a rectangular prism with a length of 4.4 cm, a width of 3.1 cm, and a height of 6.3 cm. (As before, you do not need to enter the units since they are provided to the right of the answer box.) Part C The momentum of an object is determined to be 7.2×10-3 kg⋅m/s. Express this quantity as provided or use any equivalent unit. (Note: 1 kg = 1000 g). Part D Enter the following expression in the answer box below: √2gλ3m, where λ is the lowercase Greek letter lambda.Grading for Numeric Answers Tolerance Some numeric answers to questions need to be exact.

Consider the open-loop circuit (on the left) and closed-loop circuit (on the right) shown in Figure 1 below. In this problem, the open-loop circuit (on the left) will be used to analyze the open-loop behavior of the closed-loop circuit (on the right). closed - loof ciruit Figure 1. Open-loop (left) and closed-loop (right) circuits for Problem 1. Here are the problem parameters:The NMOS devices have gmn = 6 mA/V and rdsn = 25 kΩ. The PMOS devices have gmp = 3 mA/V and rdsp = 15 kΩ. Resistor values are R1 = 1 kΩ and R2 = 3 kΩ. a) Referring to the open-loop circuit of Figure 1, determine the numerical open-loop gain Av. OL = Vout /Vin . For the purposes of this analysis, as we have done a million times before (reminder: this is the 2 nd semester of electronics, so this should not be your first electronics rodeo), you should deactivate all sources in the circuit, except Vin. . b) Referring to the open-loop circuit of Figure 1, determine the numerical open-loop output resistance Rout, oL. , i. e. , the resistance seen looking in at the output node Vout. . You should deactivate all sources in the circuit; feel free to add an appropriate test source(s), if you think you need to do that. c) Referring to the open-loop circuit of Figure 1, determine the numerical loop gain from the test source to the output node: LG = |Vout /Vtest | For the purposes of this analysis, you should deactivate all sources in the circuit, except Vtest. . Also, note that the way the loop gain is defined, it will be a positive-valued quantity. Explain why we want to use a positive loop gain for determining the closed-loop performance [see, e. g. , parts (d) and (e) below]. Your answer for this part should be both i) specific to this problem and ii) generalized to any closed-loop circuit with negative feedback. You are strongly encouraged to consider incorporating a generalized block diagram to help strengthen your argument(s). d) Referring to the closed-loop circuit of Figure 1, determine the numerical closed-loop gain Av, CL = Vout /Vin . Rather than solving the closed-loop circuit of Figure 1 directly for the closed-loop gain, you should instead utilize the results of the previous parts to determine Av, cL. Here, I need to remind you that you should do as you have been (hopefully) doing on the previous parts: first, state the equation you will use to determine Av, cL in terms of, e. g. , Av. ol. and/or Rout, ol and/or LG (i. e. , resist the temptation to dive straight into the numerical values, but feel free to write your equation in terms of Av, ol and/or Rout, ol. and/or LG instead of gmn, gmp, rdsn, rdpp , R1, R2 ), and then plug the numbers in to your equation, and then box your numerical answer along with all the things that we have expected of your numerical quantities since day one. Make it really easy for me to find the equation you used (same story for all of the parts of this problem). e) Referring to the closed-loop circuit of Figure 1, determine the numerical closed-loop output resistance Rout, CL. Rather than solving the closed-loop circuit of Figure 1 directly for the closed-loop output resistance, you should instead follow the same guidance that was given for part (d) of this problem.
