Consider the above graph of the horizontal velocity of a UFO over 30 s. The velocity peaks at 72.5 m/s after 14.5 s. Over the next 1.0 s, its velocity drops to -72.5 m/s. It then continues on with the same acceleration that it had before it changed direction. What is the UFO's net displacement after these 30 s of movement? A. 560 m
B. 0.0 m
C. 1.1 km
D. 1.5 km

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?
