PHYS 2C, W 2006 QUIZ #1 Name___________________________________ Code______________ MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question 1) An ice cube initially floats in a glass of oil. Later, it melts and the resultant water settles at the bottom of the glass. Assuming that oil and water do not mix, what happens to the fluid level? A) Rises B) Falls C) Stays the same D) Depends on oil density 1) 2) Consider a pipe whose first half - length is filled with water and the other half with oil (density 0.8 g/cm 3 ). Both fluids are incompressible. The water is made to flow with velocity 1 m/s at the front end which has the cross - sectional area of 1 m 2 . The exit cross - sectional area of the pipe is 0.5 m 2 . What is the exit velocity of the oil? A) 2.5 m/s B) 2 m/s C) 1 m/s D) 1.25 m/s 2) 3) In a bucket of water steadily rotated about its axis of symmetry, water level is known to form a dip at the center. Alice claims that this phenomenon can be explained using the Bernoulli equation plus
