it is down from horizontal drwls, Thank you for your time
Friday, December 9, 2011 at 9:59am by Jim

the angle is at the top left corner of the first block
Friday, December 9, 2011 at 9:59am by Jim

It should not matter where it was applied, as long as it was on the first block, in the downward direction you said.
Friday, December 9, 2011 at 9:59am by drwls

You need to specify if the 30 degree angle is up or down from horizontal. That will affect the friction force.

Since the light velocity in the liquid is 240,000 km/s, the refractive index is N = c/v = 300,000/240,000 = 1.25. The angle in incidence is Ai = 30 degrees. The angle of refraction (Ar) is given by Snell's Law: N*sinAr = sinAi = 0.50 sinAr = 0.40 Sr = 23.6 degrees
