A RADAR sends a signal to an aeroplane at a distance 300 km away, with a speed of 3 x 10 8 ms -1 . After how much time is the signal received back after reflecting from the aeroplane?

(a) As we know, Total distance travelled by the sound in going and then coming back = 2d Given, d = 300 km Converting km to m, we get, 1 km = 1000 m Therefore, 300 km = 3,00,000 m Hence, d = 3 x 10 5 m V = 3 x 10 8 ms -1 Substituting the values in the formula above, we get, Hence, the signal is received back after 2 x 10 -3 s
