Determine the phase difference between these two 100 Hz. (One large division in the horizontal axis equals 2 ms. A large division is indicated by the dotted line. The graph shows 10 large divisions.)

PROBLEM 5. Determine the phase difference between these two 100 Hz. (One large division in the hori 2 ms. A large division is indicated by the dotted line. The graph shows 10 large divisions.) Because you must read values from the graph, a reasonable approximation will be valid
