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
Thx dear
sorry friend i have made a mistake
It is speed =distance/time = 800/5 = 160m/s
i thought it was distance
Np dear
