Frequency is detected by the French submarine in the signal

61. A French submarine and a U.S. submarine move toward each other during maneuvers in motionless water in the North Atlantic. The French submarine moves at speed vF = 50.00 km/h, and the U.S. submarine at vUS = 67.00 km/h. The French submarine sends out a sonar signal (sound wave in water) at 1.000 x 103 Hz. Sonar waves travel at 5470 km/h. What frequency is detected by the French submarine in the signal reflected back to it by the U.S. submarine?
75. Sound waves A and B, both of wavelength lambda, are initially in phase and traveling rightward, as indicated by the two rays in the figure in the attachment. Wave A is reflected from four surfaces but ends up traveling in it's original direction. What multiple of wavelength lambda is the smallest value of distance L in the figure that puts A and B exactly out of phase with each other after the reflections?
