The following marks were recorded on air table where the time constant is adjusted at 100ms: A1A2A3 A4 A5 A6
A1A2=4cm A2A3=8cm A3A4=12cm A4A5=16cm A5A6=20cm
a) Find the average speed of the puck between A2 and A6.

What will a positive and a negative charge do if they are separated from each other?

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
