a) echo...rest i dont know

GuptaDevashish: 1.That effect is called Echo because the repetition of the sound wave after striking an object is called echo. 2. we have time is 5 seconds and distance is 800m the as we all know that speed is distance*time therefore speed of bullet = (800*5)m/s = 4000m/s

babujunnu: Thx dear

GuptaDevashish: sorry friend i have made a mistake

GuptaDevashish: It is speed =distance/time = 800/5 = 160m/s

GuptaDevashish: i thought it was distance

babujunnu: Np dear
