A torpedo moving at 32 m/s towards the east is chasing a submarine moving in the same direction at 16 m/s. If the torpedo emits sound pulses at 12.0 kHz,(a) What frequency the torpedo measures for the echo from the submarine? (b) If there is a current moving to the east at 10 m/s, what will be the answer for part a? (sonar waves travel at 5470 km/h in the seawater)(c) If the current is moving 30 degrees north of east at 10 m/s, what will be the frequency of the echo?
