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.

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
