Omega is 2pi/T whr 2pi is angular displacment in radians(for 1 oscilatn) and T is time perioad of 1 oscilatn,so omega is angular velocity here also,u cn write 1/T as frequency and 2pi is wavelngth in radians as lambda*freqency=velocity,u cn say 2pi*frequency=ang.vel.

Thank u . . .i got th same soluti0n bt i was n0t sure if th ratio of no.of nucleons equals to ratio of masses. . . .is ths always true A1/A2=M1/M2?also can v do ths by c0nsidering same density,and gettin ratio of masses fr0m ratio of volumes?
