In Fig. 25-29, nd the equivalent capacitance of the combination. Assume that C1 = 10.0 mF, C2 = 5.00 mF, and C3 =4.00 mF.

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )

in this image, you can see solar radiation going through ocean water.

no image, but probably absorption

i believe the answer is a hope it and is correct

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
