Figure E2.12 shows the velocity of a solar-powered car as a function of time. The driver accelerates from a stop sign, cruises for 20 s at a constant speed of and then brakes to come to a stop 40 s after leaving the stop sign. (a) Compute the average acceleration during the following time intervals:

The factor y in the Doppler formula (15.64), which can be ascribed to time dilation, means that even when 0 = 90 there is a Doppler shift. (In classical physics there is no Doppler shift when 6 = 90 and the source has zero velocity in the direction of the observer.) This transverse Doppler shift is t

The city of Medianville has 100 citizens with income ranging from $20,000 to $70,000. The average income is $50,000 and the median income is $60,000. An individuals demand for open space depends only on income, and the indi- vidual demand curve (marginal benefit curve) has a vertical intercept equal
