Physics Quiz

1. 1.The diagram shows a fountain of water flowing out of a container

Observations show that :

• A. The smaller the volume of water, the greater the pressure.

• B. The more the volume of water increases, the more the pressure increases.

• C. The deeper the water, the greater the pressure

• D. The lower the water depth, the higher the pressure

2. 2.The diagram shows three containers of different shapes filled with water at the same level. The water pressure at points P, Q, and R are P1, P2, and P3 respectively.

3. Which comparison is true?

• A. P1 > P2 > P3

• B. P1 < P2 < P3

• C. P1=P2 = P3

3.Diagram (a) shows a container of water before being tilted.

Diagram (b) shows the water container when tilted.

The above observation can be explained by :

• A. The speed of water flows depends on the acceleration of gravity

• B. The speed of water flows depends on the gravitational acceleration of the volume of water.

• C. water pressure depends on the density of the water

• D. water pressure depends on the depth

4.The diagram shows three wooden blocks J, K, and L pressed into the water until the base reaches the P level. The water pressure on the base of the wooden blocks J, K, and L are X1, X2, and X3 respectively.

Which comparison is true?

• A. X1 = X2 = X3

• B. X1 < X2 < X3

• C. X1 > X2 > X3
