Problem 51P (a) Compare the shift in frequency if a 2000-Hz source is moving toward you at 15 m/s, versus you moving toward it at 15 m/s. Are the two frequencies exactly the same? Are they close? (b) Repeat the calculation for 150 m/s and then again (c) for 300 m/s. What can you conclude about the

Problem 65GP Light of wavelength 590 nm passes through two narrow slits 0.60 mm apart. The screen is 1.70 m away. A second source of unknown wavelength produces its second-order fringe 1.33 mm closer to the central maximum than the 590-nm light. What is the wavelength of the unknown light?

Principles of Economics 6
Suppose the federal government requires beer drinkers to pay a $2 tax on each case of beer purchased. (In fact, both the federal and state governments impose beer taxes of some sort.) a. Draw a supply-and-demand diagram of the market for beer without the tax. Show the price paid by consumers, the pri

Urban Economics 8
Consider a region with a single factory city that developed as a result of scale economies in production. Consider the effects of a new matter transmitter, which can instantly transport goods (but not people) from the factory to any consumer up to 12 miles away, with a zero marginal cost of transport
