Aplastic cube is immersed in water having an index of refraction of 1.33. a laser beam in the plastic strikes the interface at an angle of 14.5° with the normal in the plastic. in the water, this beam makes an angle of 21.8° with the normal. what is the speed of light in the plastic cube? (c = 3.0 × 108 m/s)

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm
