Apickup truck is traveling with constant velocity up an interstate entrance ramp with a 5.50° slope. a 50.0-kg box sits on the bed of the truck and is also resting against the tail-gate of the truck. the box does not move relative to the bed of the truck. assume that there is negligible friction between the bed of the truck and the box. during an interval in which the truck travels 395 m up the ramp entrance, what is the net work done on the box?

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?
