frictionless car is released from rest on a track has a fan on top that pushes with a force of 1.3 Newtons and the mass of the car is 333 grams. A second car has a mass of 250 grams and is also released from rest with the same fan pushing it. Suppose you want the two cars to travel a distance of 2.0 meters and arrive at the same time. You can do this by adding a second fan to the second car. What magnitude of force (and in what direction) should this second fan be

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?
