Water is slowly poured into the container until the water
level has risen into tubes A, B, and C. The water doesnt
overflow from any of the tubes. How do the water depths inthe three columns compare to each other?
1. dA > dB > dC
2. dA = dC > dB
3. dA < dB < dC
4. dA = dC < dB
5. dA
= dB
= dC

An ice cube is floating in a glass of water that is filled
entirely to the brim. When the ice cube melts, the water
level will
1. stay the same, right at the brim.
2. rise, causing the water to spill.
3. fall.

The figure shows volume
flow rates (in cm3/s) for allbut one tube. What is the
volume flow rate through
the unmarked tube? Is the
flow direction in or out?
1. 1 cm3/s, out
2. 1 cm3/s, in3. 10 cm3/s, out
4. 10 cm3/s, in
5. It depends on the relative size of the tubes.

to h4 in tubes 1 to 4. The air flow is from left to right.
1. h1
> h3
> h4
> h2
2. h1 > h2 = h3 = h4
3. h2 = h3 = h4 > h1
4. h2 > h4 > h3 > h1
