A55.0-g sample of hot metal initially at 99.5oc was added to 40.0 g of water in a styrofoam coffee cup calorimeter. the water and calorimeter were initially at 21.0oc. if the final temperature of mixture was 30.5oc, calculate the specific heat capacity of the metal. the specific heat of water is 4.184 j/(g. oc) and heat capacity of calorimeter is 10.0 j/oc.

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 1.90
