a plane flies 285 miles from kansas city to st. louis at 250 miles
encounters a head wind and slows to 210 miles per hour for the rest
york city. if the plane flew 1194 miles from kansas city to new yor
to 210 miles per hour for the rest of its trip to new
w 1194 miles from kansas city to new york, what was the
average speed of the plane?

Select light for the type of wave, adjust the wavelength so that the light is red, and increase the amplitude of the light to the max. then, select the start button at the source location to begin producing the waves. light is a form of electromagnetic wave, containing oscillating electric and magnetic fields. the wave amplitude detector mentioned above shows how the electric field oscillates in time at the location of the probe. the amplitude of the wave at the location of the probe is equal to the maximum electric field measured. how does the amplitude of the wave depend on the distance from the source?
