please solve it correctly​

Answer 1

Answer:

a)0.2s

b) 300m

c) This can be due to presence of fishes much deeper than the original fish or the sea bed from which the sonar pulse takes more time to reflect and come back as it has to cover larger distance.

Explanation:

a) time for the pulse to return=2 times the time to reach the fish=0.4s

time for pulse to reach the fish=0.4/2=0.2s

b) Speed = Distance/Time

Distance = Speed x Time = 1500m/s x 0.2s = 300m

c) [Fact]
