Two simple harmonic motions are represented by the equations y1 = 0.1sin (100 πt + 3/π ) and y2 ​= 0.1cos πt. The phase difference of the velocity of particle 1 with respect to velocity of particle 2 is

the frequency of oscillation becomes Two springs of force constants k1 and k2 are connected to a mass m as shown below. The frequency of oscillation of the mass is f. If both k1 and k2 are made four times their original values
