1. The two particles have the same amplitude and period in theirrespective simple harmonic vibration. The vibration equation of the firstparticle is 21 = A cos(wt + a). When the first particle returns toits equilibrium position from its positive displacement with respect to itsequilibrium position, the second particle is at its maximum positivedisplacement. Then the vibration equation of the second particle is Multiple-Choice (10 Points) O A. x2 = A cos(wt+a+/2) O B.x2 = A cos(wt+a-3/2) O C. 22 = A cos(wt+a+7) O D. x2 = A cos(wt+a - 7/2) 2. For the plane simple harmonic with frequency of 100 Hz andpropagation speed of 300 m/s, the phase difference between the vibration of twopoints separated by a distance less than a wave length along the wavepropagation direction is 7/3, then the two points are separated by Multiple-Choice (10 Points) O A.2.19 m. OB. 0.25 m. O C. 0.5 m. O D. 2.86 m.
