21. coherent, monochromatic light of wavelength 720 nm is incident on two closely-spaced, very narrow slits. the distance between the slits, the distance to the viewing screen behind the barrier, and location of the bright and dark spots have not been measured. we can conclude that light leaving the more distant slit which arrives at the 2nd dark spot relative to the central bright spot has traveled an extra distance of relative to the closer slit.

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.

The drag force, fd, imposed by the surrounding air on a vehicle is given by: = 1 2 2 where cd is a constant called the drag coefficient, a is the projected frontal area of the vehicle, is the air density and v is the velocity. determine the power, in hp, required to overcome aerodynamic drag for an automobile moving at a) 40 mph and b) 80 mph. find these values for a honda civic which has a cd = 0.36 and a = 21.8 ft2 , when the air has a specific volume of 13.3 ft3 /lbm
