(III) An atomic nucleus of mass m traveling with speed v collides elastically with a target particle of mass 2m (initially at rest) and is scattered at \(90^{\circ}\). (a) At what angle does the target particle move after the collision? (b) What are the final speeds of the two particles? (c) What fra

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

Consider the Dinks (double income, no kids). Mr. Dink commutes to a job in the city center (x=0), while Ms. Dink commutes to a suburban subcenter four miles east of the city center. The Dinks consume the same quantity of housing at all locations. Travel speed is the same in both directions. a . Draw

Complementary and Substitute Products In Exercises 63 and 64, determine whether the demand functions describe complementary or substitute product relationships. Using the notation of Example 4, let \(x_1) and \(x_2\) be the demands for two products whose prices are \(p_1\) and \(p_2\), respectively.
