Atank holds a 1.44-m thick layer of oil that floats on a 0.96-m thick layer of brine. both liquids are clear and do not intermix. point o is at the bottom of the tank, on a vertical axis. the indices of refraction of the oil and the brine are 1.40 and 1.52, respectively. a ray originating at o reaches the brine-oil interface at the critical angle. what is the distance of this point from the axis?

In a system, when potential energy decreases, then entropy also decreases. true false

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
