Contact lenses are designed to be gas permeable in order to allow oxygen to diffuse to the eye. if the edge of a contact lens is double the thickness of the central portion of the lens, how will the diffusion time differ through the different parts of the contact lens?
a) the diffusion time through the edge is double the diffusion time through the center.
b) the diffusion time through the edge is quadruple the diffusion time through the center
c) the diffusion time through the edge is half the diffusion time through the center
d) the diffusion time is the same for both.

Ahot-air balloon is drifting straight downward with a constant speed of 2.40 m/s. when the balloon is 7.63 m above the ground, the balloonist decides to drop one of the ballast sandbags to the ground below. how much time elapses before the sandbag hits the ground?

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

The temperature at a point (x, y) is t(x, y), measured in degrees celsius. a bug crawls so that its position after t seconds is given by x = 6 + t , y = 8 + 1 3 t, where x and y are measured in centimeters. the temperature function satisfies tx(3, 9) = 5 and ty(3, 9) = 4. how fast is the temperature rising on the bug's path after 3 seconds? (round your answer to two decimal places.)
