Follow the steps above to solve the problem: a diamond is underwater; a light ray enters one face of the diamond, then travels at an angle of 30 degrees with respect to the normal. what was the ray's angle of incidence on the diamond? the index of refraction of water is nwater=1.33, and the index of refraction of diamond is ndiamond=2.42.

In a stagnant pool of water, a crayfish may spend much of its time lying with one side of its carapace near the surface of the water. in this position, it will move the walking legs on that side in a rhythmic back-and-forth motion. explain the likely function of this behavior.

Asolid round steel rod 6.25 mm in diameter and 375 mm long is rigidly bonded to the end of solid square brass rod 25 mm on a side and 300 mm long. the geometric axes of the bare are along the same line. an axial tensile force of 5.4 kn is applied at the extreme ends of the assembly. for steel e = 200 gpa and for brass e = 90 gpa. determine the total elongation for the assembly.
