In a certain material, a beam of monochromatic light (f=5.09 × 10^14 Hz) has a speed of 2.04× 10^8 meters per second. The material could be Question 14 options:

crown glass (n=1.52)

flint glass (n=1.66)

glycerol (n=1.47)

water (n=1.33)

Use the profile illustrated for problem (1). assume that the layer of silty sand fill (sm) is placed over the entire site. estimate the thickness of the fill (h - in feet) that will cause the effective vertical stress at the center of the clay layer to increase by 517.5 pounds per square foot.

Consider an ideal gas at 27.0 degrees celsius and 1.00 atmosphere pressure. imagine the molecules to be uniformly spaced, with each molecule at the center of a small cube. what is the length l of an edge of each small cube if adjacent cubes touch but don't overlap?

The junction rule describes the conservation of which quantity? note that this rule applies only to circuits that are in a steady state.
