Hi, I'm a junior and I have been assigned a lab that I has completely me blown away! We are to find the intensity of our given light source on a solar panel at different distances. My partner and I understand how to complete the lab, but there is another part of the grade. We are assigned to write 3 pages about the intensity of light and we don't even know where to start. If anyone could point us in the right direction for valid information on the topic, that would be fantastic. (:

The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
