You want to build a Mercury thermometer where the distance between the -5°C and the 35°C markings is equal to 20cm. Knowing that you have a capillary with cross section σ = 0.1mm2 , what is the volume of the bulb that you have to use? volumetric expansion coefficient of Mercury β = 0.182 ◦1/C

1.what is where an object is located 2. what is how fast an objects speed is changing 3. what is how fast an object is moving

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

Which sections of the heating curve illustrate this process?
