  1. Period 2Question 1

  2. 60 A large stone is resting on the bottom of a pool. With what force does the stone push on the bottom of the pool? • The weight of the stone • The weight of the water displaced • The sum of the weight of the stone and the displaced water • The weight of the stone minus that of the displaced water

  3. Period 2Question 2

  4. An ideal fluid flows through a pipe made of two sections with diameters 3 and 1 inches respectively. The speed of the fluid flow through the the 3 inch section as compared to the 1 inch section is: • The same • 3 times faster • 3 times slower • 9 times faster • 9 times slower

  5. Period 3Question 1

  6. 60 Ice has lower density than the water, and it floats in a glass of water with about 10% of the ice being above the water surface. What happens to the water level in the glass when all the ice melts? • The water level rises 10% • The water level rises less than 10% • The water level remains unchanged • The water level is lowered 10%

  7. Period 3 Question 2

  8. An ideal fluid flows through a pipe made of two sections with diameters 1 and 2 inches respectively. The speed of the fluid flow through the the 1 inch section as compared to the 2 inch section is: • The same • Twice faster • Twice slower • 4 times faster • 4 times slower
