Assume that the op-amp shown below is ideal. Find vo(t) for all t. Solution I. The output attempts to do whatever is necessary to make the voltage difference between the inputs zero. II. The inputs draw no current. Comments on 1: The voltage gain of a real op-amp is so high that a fraction of a millivolt input will swing the output over its full range. Practically, that amounts to rule 1. Comments on 2: The input current is so low (0.08 microamps for ...

MATLAB programming question: Write a function called that takes in one argument, a matrix, performs gaussian elimination utilizing a partial pivoting strategy and elementary row operations only. Your function must not perform any permutations of the columns of the input matrix. Your function must return the the row echelon form of the input matrix. Before returning, your function must print the determinant of the input matrix. You may not use any of the following built in functions: det, lu...

Two 1.5g beads, each charged to 5.5nC , are 1.8cm apart. A 3.0g bead charged to -1.0nC is exactly halfway between them. The beads are released from rest. A) What is the speed of the positive beads, in , when they are very far apart? (cm/s) Solution Initial PE on both the positive charges is same = PE due to Negative charge + PE due to another positive charge Therefore initial PE = ( K (5.5 x 10-9)(5.5 x 10-9) / 0.018 ) + ( K (5.5 x 10-9)(-1 x 10-9) / 0.009 ) = 1.748 x 10-6 J At...

In a job-order costing system, the amount of overhead cost that has been applied to a job that remains incomplete at the end of a period: a. is transferred to Finished Goods at the end of the period. b. is part of the ending balance of the Work in Process inventory account. c. is deducted on the Income Statement as overapplied overhead. d. is closed to Cost of Goods Sold. Solution B.) is part of the ending balance of the Work in Process inventory ac...

One example is the diets of human ancestors. What are some other applications of nitrogen isotopes? Solution N-14 and N-15 are the isotopic forms of nitrogen. N-15 is used to produce radioisotope O-15 N-15 is also used to assess the uptake of Nitrogen in plants and the metabolism of proteins in humans. N-14 is used to produce radioisotope C-11. N-14 is also used to produce radioisotopes N-13 and O-15.

How much heat is required to melt 15 grams of ice at 0C? How much heat is released when 100 grams of steam condenses at 100C? If a system of ice and water has a mass of 12 grams, and it is converted completely to water at 0.0C by supplying 1.33 kJ of heat, how much water was initially present? Heat of fusion of ice = 333 J/g Heat of vaporization of water = 2250 J/g Is there a formula to help solve these problems? Solution change the number plz 1. The heat of fusion of water ...

Animals evolved large body size gradually. But why this trend? Solution Ans: Animals evolved large body size gradually. This trend is because: - Humans and many other animals tend to evolve larger body sizes over time. - Cope's rule holds that there is active selection for increasing body size in nature. - It appears that evolution follows certain rules and can, at least to some extent, be predicted. - Advantages associated with a large size, such as ability to move faster, to bu...

Sled Manufacturing budgeted 10,000 widgets for production during 2012. Sled has capacity to produce 12,000 units. Fixed factory overhead is allocated to production. The following estimated costs were provided: Direct material ($14/unit)$ 140,000 Direct labor ($30/hr. Solution Hi, Part 1 Sales Value (1000*86) = 86000 Variable Cost Direct Material (1000*14) = 14000 Direct Labor (1000*2*30) = 60000 Variable Manu. Overhead (1000*6) = 6000 Contribution = 86...

Find the x and y intercepts of the line whose equation is:3x-2y=12 Solution 3x - 2y = 12. -2y = - 3x + 12. dividing by 2 the whole equation to seperate the y. y = (3/2)x - 6. y intercept = - 6. so y intercept is    y = -6 to find the x-intercept consider the equation again. 3x = 2y + 12 divide y 3 the whole equation to seperate the x. x = (2/3)y + 4. x intercept = + 4 so x intercept is x = +4

Does the company Dell use the single-step income statement, multiple-step income statement, or a variation of both? Explain Solution Dell company uses a 'Multiple Step Income Statement'. A multiple step income statement separates the operating revenues and operating expenses from the nonoperating revenues, nonoperating expenses, gains, and losses. The multiple-step income statement also shows the gross margin or gross profit (net sales minus the cost of good...
