Me1 Problem Set #2 The US College Enrollment and the “Third Law of Demand” A theorem proposed by Professors Alchian and Allen in their text‚ University Economics (1964) has had several rebirths of interest in the literature. The so-called “third law of demand‚” or “relative price theorem‚” holds that a fixed cost added to a good of varying quality causes the consumer to prefer the category considered of higher quality to the lower. Recently a number of studies‚ keeping this theorem in mind have

heat is produced in one minute? ( Nichrome = 100 x 10-8 Ω-m) Given: A = .05 mm2 = (.05)(10-3)2 = .05 x 10-6 m2 ‚ and L = 50 cm = .5 m . Formula: R = ρL/A Solution: R = (100 x 10-8)(.5)/(5 x 10-8) R = 10 ohms 7. A nine volt battery supplies power to a cordless curling iron with a resistance of 18 ohms.
