When radio waves try to pass through a city, they encounter thin vertical slits: the separations between the buildings. this causes the radio waves to diffract. in this problem, you will see how different wavelengths diffract as they pass through a city and relate this to reception for radios and cell phones. you will use the angle from the center of the central intensity maximum to the first intensity minimum as a measure of the width of the central maximum (where nearly all of the diffracted energy is found).a. find the angle θ to the first minimum from thecenter of the central maximum (express your answer in terms λ and a.): b. what is the angle θfm to the first minimum foran fm radio station with a frequency of 101mmhz? (express your answer numerically indegrees to three significant figures. note: do not write youranswer in terms of trignometric functions. evaluate any suchfunctions in your working.)c. what is the angle θcell for a cellular phonethat uses radiowaves with a frequency of 900mhz? (express your answer indegrees to three significant figures.)d. what problem do you encounter in tryingto find the angle θam for an am radio stationwith frequency 1000khz? i. the angle becomes zero. ii. the angle can be given only in radians. iii. to find the angle it would be necessary to takethe arcsine of a negative number. iv. to find the angle it would be necessary totake the arcsine of a number greater than one.

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?

The bar of prob. 5/82 is repeated here. the ends of the 0.4-m bar remain in contact with their re- spective support surfaces. end b has a velocity of 0.5 m/s and an acceleration of 0.3 m/s2 in the di- rections shown. determine the angular accelera- tion of the bar and the acceleration of end a.
