Question 1
The water level in a reservoir is maintained at a constant level. What is the exit velocity in an outlet pipe 3.0 m below the water surface?
◦
2.4 m/s
◦
3.0 m/s
◦
5.4 m/s
◦
7.7 m/s
◦
49 m/s
Question 2
The water level in identical bowls, A and B, is exactly the same. A contains only water; B contains floating ice as well as water. When we weigh the bowls, we find that
◦
WA<WB.
◦
WA = WB.
◦
WA>WB.
◦
WB>
WA if the volume of the ice cubes is greater than

the volume of the water.
◦
WB>WA if the volume of the ice cubes is greater than 9 times the volume of the water.
