Two people start at the same place and walk around a circular lake in opposite directions. One has an angular speed of 2.42 x 10-3 rad/s, while the other has an angular speed of 6.90 x 10-3 rad/s. How long will it be before they meet?

50.)the diagram below represents the wave fronts produced by a point source moving to the right in a uniformmedium. observers are located at points a and b.compared to the wave frequency and wavelength observed at point a, the wave observed at point b has a(1) higher frequency and a shorter wavelength(2) higher frequency and a longer wavelength(3) lower frequency and a shorter wavelength(4) lower frequency and a longer wavelength
