Answer: X 108m/s Time = 0.02 milliseconds = 0.02 x 10-3 secondsNow, using the formula, ... A radar is able to detect the reflected waves from an enemy aero plane, after a time interval of 0.02 milliseconds. If the velocity of the waves is 3 x 108m/s, calculate the distance of the plane ... Time = 0.02 milliseconds = 0.02 x 10-3 seconds
