Period 2 Question 1

A large stone is resting on the bottom of a pool 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 60

Period 2 Question 2

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

Period 3 Question 1

The water level rises less than 10% The water level remains unchanged 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% 60

Period 3 Question 2

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
