The University of Minnesota uses thousands of fluorescent light bulbs each year. The brand of bulb it currently uses has a mean life of 900 hours. A manufacturer claims that its new brand of bulbs, which cost the same as the brand the University currently uses, has a mean life of more than 900 hours. The university has decided to purchase the new brand if when tested , the test evidence supports the manufacturer’s claim at the 10% significance level, Suppose 81 bulbs are tested and their mean is 920 hours with a s. d. of 80 hours.

5. In the figure drawn below, A long straight wire (a) carries current of 150 A passing to the right. There is a light conducting rectangular loop (b) hangs vertically to the long wire by two insulating strings of length 5.0 cm. Mass of the loop is 0.40 g and its dimensions are 20. cm by 7.0 cm. What current must circulate through the loop (b) and in what direction so that the tension in the insulating strings becomes zero? (10 points) $I = 150 A$

Given: qd = 50 - p, qs = 20 + p To find eq and ep, we need to solve for p in both equations. qd = 50 - p qs = 20 + p To find eq, we set qd equal to qs: 50 - p = 20 + p To find ep, we set qd equal to 0: 50 - p = 0 Now, let's solve for p in both equations. For eq: 50 - p = 20 + p To isolate p, we can add p to both sides: 50 = 20 + 2p Next, subtract 20 from both sides: 30 = 2p Finally, divide both sides by 2: 15 = p Therefore, eq = 15. For ep: 50 - p = 0 To isolate p, we can subtract 50 from both sides: -p = -50 Next, multiply both sides by -1 to change the sign: p = 50 Therefore, ep = 50. Now, let's find the new qd and qs when the curve shifts to 40 + 3p. To find the new qd, we substitute the new equation into qd: qd = 40 + 3p To find the new qs, we substitute the new equation into qs: qs = 20 + p Therefore, the new qd is 40 + 3p and the new qs is 20 + p.
