Water is slowly poured into the container until the water
level has risen into tubes A, B, and C. The water doesn’t
overflow from any of the tubes. How do the water depths in
the 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

Rank in order, from largest to smallest, the magnitudes of
the forces                required to balance the masses.
The masses are in kilograms.
                    1.   F2 > F1 > F3
                    2.   F2 > F1 = F3

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 all
but one tube. What is the
volume flow rate through
the unmarked tube? Is the
flow direction in or out?
