Crocodiles often float with their eyes just above water. They manipulate their buoyancy both by adjusting the volume of their lungs and by swallowing rocks (gastrolithes). A 120 kg crocodile swallows gastrolithes that are 0.8% of his mass to sink to a lower level. How much would it have to increase its lung volume in mL to counteract the sinking effect? Assume that the air pressure in its lungs is not much greater than atmospheric pressure.

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?
