Procedure: 1. The compass was placed on the lab table with no magnets nearby to identify what direction was north relative to the classroom. 2. On the ends of the variable gap magnet there were two small magnetic disks. One arm of the magnet was unscrewed and removed from its housing. A meter stick was placed on the and the arm was on its side parallel to the meter stick. The Gauss-Tesla meter was used to measure the field strength of the magnet. The probe attached to the meter was perpendicular

more than 1 Blu-ray player fails to meet specifications. Otherwise‚ the entire day’s production has to be tested. (a) What is the probability that the engineer incorrectly passes a day’s production as acceptable if only 85% of the day’s Blu-ray players actually conform to specification? From the given information‚ we can know both problems are n Bernoulli Trials‚ where n 13 . Suppose p is probability that the engineer passes a day’s production

Answer (i) Mass of one electron = 9.10939 × 10–31 kg Number of electrons that weigh 9.10939 × 10–31 kg = 1 Number of electrons that will weigh 1 g = (1 × 10–3 kg) = 0.1098 × 10–3 + 31 = 0.1098 × 1028 = 1.098 × 1027 (ii) Mass of one electron = 9.10939 × 10–31 kg Mass of one mole of electron = (6.022 × 1023) × (9.10939 ×10–31 kg) = 5.48 × 10–7 kg Charge on one electron = 1.6022 × 10–19 coulomb Charge on one mole of electron = (1.6022 × 10–19 C) (6.022 × 1023) = 9.65 × 104 C Question

Morgan Trahan 10/02/2014 Unit 3 Assignment 1 Lymphatic filariasis is an extremely painful infection of the lymphatic system. It is caused when thread-like filarial parasites are transmitted to humans through mosquitoes. There are three forms of the parasites which are Wuchereria bancrofti‚ Brugia malayi and Brugia timorican. The most common is Wuchereia bancrofti. When the mosquito bites the human‚ it injects the larvae into the blood stream which then circulates into the lymphatic system. The
