In Fig. , a French submarine and a U.S. submarine move toward each other during maneuvers in motionless water in the North Atlantic. The French sub moves at the speed v_v = 48.00 km/h, and the U.S. sub at v_(US)= 72.00 km/h. The French sub sends out a sonar signal (sound wave in water) at 1.560 xx 10^3Hz. Sonar waves travel at 5470 km/h. (a) What is the signal's frequency as detected by the U.S. sub? (b) What frequency is detected by the French sub in the signal reflected back to it by the U.S. sub? |
| Answer» SOLUTION :`(a) 1.595 XX 10^3 HZ, (B ) 1.630 xx 10^3 Hz` | |
