Question

13 2: What is the equivalent resistance? Think about the flow of current. Resistances are in series only when they have exactly the same current. Resistances are in parallel when their 'legs' are connected on one side and on the other side. Do this in a couple of steps. Rseries = R1 + R2 + R +... het is + Rparallel V=IR 3: 110.80 52.17 230

Answer 1

Full information was not given for first question. So I assumed that you only asked the answer of second question.

3x108 m/s C= Warelength of the people light, 1-1900m speed of light, so frequency, f= À = 440nm 440x10-9m 3x108 Hz 440x10 f = 608 81019 Hz. -g so, frequency of the purple 14 6. 8 X10 light is
