A Gaussian sphere of radius 0.5 m contains a number of charged particles producing a total electric flux of magnitude ( going through the sphere. There are no charges outside of the sphere but it is surrounded by a larger Gaussian sphere of radius 1.0 m, and the Gaussian spheres are arranged such that their center-to-center distance measures to be 10 cm. So, they are almost concentric.
An OTR is evaluating an outpatient client who had surgery 6 days ago for open reduction and internal fixation of a spiral fracture to the right humerus. The client has an associated radial nerve injury with no active movement at the wrist and hand. What action should the OTR take during this stage of recovery? A. Fabricate a low-profile orthosis with wrist positioned in slight extension and dynamic extension of MCP joints of fingers and thumb. B. Provide a prefabricated wrist support with the wrist positioned in neutral allowing free ROM of fingers and thumb. C. Fabricate high-profile dynamic extension orthosis for wrist, finger, and thumb extension.

Concord Corporation had a 1/1/20 balance in the Allowance for Doubtful Accounts of $38,500. During 2020, it wrote off $29,000 of accounts and collected $8,600 on accounts previously written off. The balance in Accounts Receivable was $810,000 at 1/1 and $940,000 at 12/31. At 12/31/20, Concord estimates that 5% of accounts receivable will prove to be uncollectible. What is Bad Debt Expense for 2020? Answer is $28,900. Please show work. Thank you.
Texts: An entrepreneur manufactures braai drums. He builds two types: an Ordinary model and a De Luxe model. With the labor and equipment that he has available, he can build 150 Ordinary and 120 De Luxe models per month, but not more than a total of 200 drums per month. He has fixed orders of 40 Ordinary and 10 De Luxe models per month. The guy makes R50 profit on each Ordinary braai drum and R100 on every De Luxe model. Let the number of Ordinary models manufactured per month be x and let the number of De Luxe models manufactured per month be y. 7.1 Write down all the constraints for this scenario. (5) 7.2 Choose in each case the correct answer and write down only the letter of the correct answer, e.g. 7.2.1C. 7.2.1 The objective function for the total amount of profit that the entrepreneur makes per month is given as: A. 50x+100y B. P=50x+100y C. P=150x+120y D. P=100x+50y 7.2.2 The coordinates of the vertices of the feasible region of this scenario are the following: K(40;10), L(40;120), R(80;120), S(150;50), T(150;10). Use the objective function together with these vertices to determine at which point the entrepreneur will make maximum profit. A. At vertex L(40;120) B. At vertex R(80;120) C. At vertex S(150;50) D. At vertex T(150;10) 7.2.3 How many of each type must he manufacture per month to make maximum profit? A. 40 Ordinary and 120 De Luxe B. 80 Ordinary and 120 De Luxe C. 150 Ordinary and 50 De Luxe D. 150 Ordinary and 10 De Luxe 7.2.4 What is the maximum profit he can make per month? A. R14000 B. R16000 C. R12500 D. R8500 (2) TOTAL 50
11) Why is it necessary to balance the output capacitive loads in DRP logic styles? (Multiple choice) a) To prevent the adversary from deciding whether the true or complementary wires are being switched b) To maintain the clock specification c) To minimize power consumption d) To reduce the noise levels because of signal reflections that occur because of mismatch
