Using the physical conditions present in the universe during the era of recombination (T=3000 and pm=10^-18 kg/m^3), show by calculation that the Jeans length for the universe at that time was about 100 ly and that the total mass contained in a sphere with this diameter was about 4×10^5 Msun.
Explain the two methods for reducing total product costs to achieve a desired target cost. Which is more common in the consumer electronic industries? In the specialized equipment manufacturing industries?
Calculate the measured resistance of a resistor and verify the Ohm’s law. Please see attached file. On a separate piece of graph paper, plot V against I and connect the points with a smooth curve. The V-I curve for two elements in series can also be calculated from the V-I curve of the individual elements. […]
1. Organ pipe A, with both ends open, has a fundamental frequency of 300 Hz. The third harmonic of organ pipe B, with one end open, has the same frequency as the second harmonic of pipe A. How long are (a) pipe A and (b) pipe B? 2. A tuning fork of unknown frequency makes […]
Please see the attached file. Let A_n be a sequence of subsets of a given set X, and let J be the set of all x in X that are in infinitely many A_n. Show that J is equal to the intersection (from n = 1 to infinity) of [the union (from i = n […]
Wilbur Corporation is considering replacing a machine. The replacement will cut operating expenses by $24,000 per year for each of the five years that the new machine is expected to last. Although the old machine has a zero book value, it has a remaining useful life of five years. The depreciable value of the new […]
