1.	A bat emits ultrasonic wave, which returns back to the bat after being reflected from its prey in 4 s. How far is the prey? (Assume speed of sound in air as 345 m/s)
Answer» Speed = 345 m/secTime = 4 secSpeed = distance/timeTherefore, distance = speed × time= 345×4= 1380The prey is 1380 m away.Hope it helps!Kindly MARK as BRAINLIEST :)
