1.	A sound detector D moves with constant speed on a circle or radius R and centre at O in xy plane. A pointsource of sound S lines in xy plane at a distance 2R from the point O and emits sound of a given frequnecy . The ratio of maximum frequencyrecorded by the detector is 11/9 and speed of sound is 340 m/s . the minimum time interval in seconds between reacording a maximum frequency and mimmim frequency is (takeR = 17)
