Then second one starts beating the drum and now first one hear the sound after time `t_(2)`. Calculate the velocity of sound relative to air and the velocity of wind, if it is blowing from first bank to the other bank at right angle to the river flow |
Answer» Correct Answer - `[(1)/(2)((1)/(t_(1)) + (1)/(t_(1))), (l)/(2) ((1)/(t_(1)) - (1)/(t_(2)))]` |
