Two rocks are simultaneously dropped into a pond, creating the ripples shown. As they overlap, the ripples interfere. At the point marked with a dot, A. The interference is constructive. B. The interference is destructive. C. The interference is somewhere between constructive and destructive. D. There's not enough information to tell about the interference. What is the extra distance As traveled by one wave to the dot compared to the other? Α. Ο C. A 31 D. F. 4 5A B. E. 21 R, R, R I2 I3 Select all loop rules that apply to this circuit. SELECT ALL THAT APPLY A. 0 = -V +1,R2 – 1R1 B. 0 = V2 – 13R3- lR2 – Vị C. 0 = 4R1 – V2 – I3R3 D. 0 = -V – 1R2 + I¼R1 E. 0 = -V2 – I3R3 + 1½R2 +V1 F. 0 = 1, R, +V2 + I,R3 G. 0 = -V +I,R2 + I,Rq H. 0 = V2 + I3R3 + 1,R2 – V1 I. 0 = 1,R1 - V2 + I3R3 J. 0 = -V- I½R2 + I, R1 K. 0 = -V2 + I3R3 + 12R2 - V2 L. 0 = -1,R – V½ – 13R3 wwT ww
