3 slices of a partially eaten 12-inch pizza are shown above. The CM of the entire uneaten pizza is cm = - 1.4 in. and yox= - 1.4 in, as shown.
(a) Assuming that each remaining slice is identical, find the CM of each slice. Choose the origin as shown above.
Starting with the slice in Q2 and going cow give the 3 CM's in the (x, y) format.
HINT: By symmetry, the positions of the CM of each slice must be the same distances x and y from the middle of the
pizza.
(b) Is the crust of the pizza stuffed with cheese? Prove your answer.

People with normal vision cannot focus their eyes underwater if they aren't wearing a face mask or goggles and there is water in contact with their eyes. in a simplified model of the human eye, the aqueous and vitreous humors and the lens all have a refractive index of 1.40, and all the refraction occurs at the cornea, whose vertex is 2.60 cm from the retina.with the simplified model of the eye, what corrective lens (specified by focal length as measured in air) would be needed to enable a person underwater to focus an infinitely distant object? (be careful-the focal length of a lens underwater is not the same as in air! assume that the corrective lens has a refractive index of 1.62 and that the lens is used in eyeglasses, not goggles, so there is water on both sides of the lens. assume that the eyeglasses are 2.05cm in front of the eye.)
