Two radio antennas separated by d = 272 m as shown in the figure below simultaneously broadcast identical signals at the same wavelength. A car travels due north along a straight line at position x =

1 330 m from the center point between the antennas, and its radio receives the signals. Note: Do not use the small-angle approximation in this problem.

(a) If the car is at the position of the second maximum after that at point O when it has traveled a distance y = 400 m northward, what is the wavelength of the signals?
m

(b) How much farther must the car travel from this position to encounter the next minimum in reception?
m

Two radio antennas are 140 m apart on a north-south line. The two antennas radiate in phase at a frequency of 5.2 MHz. All radio measurements are made far from the antennas. The smallest angle, reckoned east of north from the antennas, at which constructive interference of two radio waves occurs, is closest to: 28

Two concentric spheres are shown in the figure below.

Two concentric spheres are shown in the figure below. The inner sphere is a solid conductor and carries a charge of +5.00 μC uniformly distributed over its outer surface. The outer sphere is a conducting shell that carries a net charge of -8.00 μC. No other charges are present. The radii shown in the figure have the values R1 = 10.0cm, R2 = 20.0cm, and R3 = 30.0 cm.
