Problem 1: Two out-of-phase radio antennas at a: :I: 300 m on the m-axis are emitting 3.0 MHZ radio waves. Is the point (my) = (300 m,800 m) a point of maximum constructive interference, perfect destructive interference, or something in between? Problem 2: When mass M is tied to the bottom of a long, thin wire suspended from the ceiling, the Wire's second-harmonic frequency is 200 Hz. Adding an additional 1.0 kg to the hanging mass increases the second-harmonic frequency to 245 Hz. What is M
