What is the emf of the battery? You connect a battery, resistor, and capacitor as in (Figure 1), where R=16.0\Omega and C=9.00\times 10^(-6)F. The switch S is closed at t=0. When the current in the circuit has magnitude 3.00 A , the charge on the capacitor is 40.0\times 10^(-6)C. Figure 1 of 1 ◻ Request Answer Part B At what time t after the switch is closed is the charge on the capacitor equal to 40.0\times 10^(-6)C ? Express your answer with the appropriate units. t= ◻ Request Answer Part C When the current has magnitude 3.00 A , at what rate is energy being stored in the capacitor? Express your answer with the appropriate units. ◻ Request Answer Part D When the current has magnitude 3.00 A , at what rate is energy being supplied by the battery? Express your answer with the appropriate units.

IV. Below is the figure of two plates from the Heat shock transformation experiment. Which of the following statements is False? Bench 1, Plasmid (-) Heat shock (+) Bench 1, Plasmid (+) Heat shock (+) Plate A Plate B Ampicillin + X gal Ampicillin + X gal A. The Heat shock transformation worked because while plate B had blue colonies, there were no blue colonies at all in plate A. B. Ampicillin was added on the plates to only select for cells that had taken up the plasmid containing ampicillin resistance gene called beta galactosidase. C. X gal was added on the plates to confirm the presence of plasmid as blue colonies because the plasmid encodes for LacZ enzyme that can break down X gal into a blue product. D. Colonies on plate A have become somehow ampicillin resistant although they do not have plasmids. E. If we do not add ampicillin on the plate, we would still get lots of blue colonies because the plasmid encodes for LacZ enzyme that can break down X gal into a blue product. F. B and E G. D and E

Make-or-Buy Decision Pizana Computer Company has been purchasing carrying cases for its portable computers at a purchase price of $56 per unit. The company, which is currently operating below full capacity, charges factory overhead to production at the rate of 41% of direct labor cost. The unit costs to produce comparable carrying cases are expected to be as follows: Direct materials $30.00 Direct labor 18.00 Factory overhead (41% of direct labor) 7.38 Total cost per unit $55.38 If Pizana Computer Company manufactures the carrying cases, fixed factory overhead costs will not increase and variable factory overhead costs associated with the cases are expected to be 12% of the direct labor costs. a. Prepare a differential analysis dated May 31 to determine whether the company should make (Alternative 1) or buy (Alternative 2) the carrying case. Round your answers to two decimal places.

In 1997, a survey of 920 households showed that 157 of them use e-mail. Use those sample results to test the claim that more than 15% of households use e-mail. Use a 0.05 significance level. Use this information to answer the following questions. H0 = 0.15 H1 > 0.15 b. What is the test statistic? (Round to two decimal places as needed.) c. What is the P-value? (Round to three decimal places as needed.) d. What is the conclusion? There is not sufficient evidence to support the claim that more than 15% of households use e-mail. There is sufficient evidence to support the claim that more than 15% of households use e-mail. Is the conclusion valid today? Why or why not? A. Yes, the conclusion is valid today because the requirements to perform the test are satisfied. B. No, the conclusion is not valid today because the population characteristics of the use of e-mail are changing rapidly. C. You can make no decisions about the validity of the conclusion today.
