1. The diagrams show, to the same scale, the vertical sections of a set of circular vessels, each containing the same depth of water. Which one of the following statements is correct?
2. A gas is trapped inside a cylinder by a movable piston. The length of the gas column is 50 cm and the pressure inside the cylinder is p.

The piston is pushed in a distance of 30 cm, so that the length of the gas column is now 20 cm. The temperature of the gas does not change.

What is the new pressure of the gas?
3. The diagram shows a glass block resting on a table top. The area of the block in contact with the table is X and the area of the table top is Y.

The weight of the block is P and the weight of the table is Q.

Which expression gives the pressure exerted on the table by the block?
4. Bubbles of gas, escaping from the mud at the bottom of a deep lake, rise to the surface. As the bubbles rise, they get larger.

Why is this?
5. The diagram shows a manometer containing mercury that is sealed at one end. What happens to the distance h when the manometer is taken to the top of a mountain?
6. A brick of weight 80 N stands upright on the ground as shown. What is the pressure it exerts on the ground?
7. A block of wood measuring 5 m long, 4 m wide and 0.5 m thick is placed on a table. Find the pressure exerted on the table due to the block if the mass of the block is 4000 kg.
8. Which of the following does not affect the pressure beneath the surface of a liquid?
9. Which of the following will cause the height of the mercury column in a barometer, A, to be higher than  that of another barometer, B, located at sea level?
10. A manometer is connected to a gas supply. Pressure can be measured in cm of water.

What is the pressure of the gas?

1. How The question no.6 answer is 2000 pascal?
Its supposed to be 200 pascal, with the rule .
P=F/A
P=4000/5×4
= 4000/20
=200.

How 2000?

• m=4000kg
P=mg/A
P=4000*10/5*4
P=2000

2. Can anyone explain me that how the answer of mcq no7 is p/3

• idk either

• • Height of the liquid column increased by 40 cm, which means new height is 60 cm. volume increases 3 times, which in turn makes the pressure decrease to 1/3 so answer is p/3

3. how can i get the answers….

4. I think here, in question 9 the answer (a) shall be
5.0 x 10^-3
5.0 x 10^3

• Can you show how you arrive at $5.0 \times 10^{-3}$?

• its 5.0 x 10^4

5. physics

• same bro

6. How can i get the answers of this quiz

• @Aisha
You have to answer the quiz and you will get the correct answers upon the submission of the answers you gave to the questions.

• Click on “I am not a robot” which is at the bottom section of the page.
Then click “Submit”.
And the checked page will be opened.

7. Would you kindly assist me in these questions i do not have enough information to tackle them and i am getting myself more confused.Thanks…
