The largest blocks in the Great Pyramid weigh 15 tons (about 13,600 kg). Dragging such a block up a ramp with a mechanical advantage of 3 would
require a force of 4.5 104 N. If 9.0 105 J of work was done on the block to
move it up the ramp, neglecting friction, how far was the block moved?

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
