1. The diagram above shows a cylindrical container with diameter 0.5 m containing a liquid of density 750 $kg \, m^{-3}$. Find the pressure exerted by the liquid on the base of the container.
2. A manometer is connected to a gas supply.

Pressure can be measured in cm of water.

What is the pressure of the gas?
3. A barometer is carried up on a balloon. Why does the reading on the barometer fall?
4. 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?
5. The diagram shows a simple mercury barometer. Which height is a measure of the atmospheric pressure?

6. 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?
7. Which of the following does not affect the pressure beneath the surface of a liquid?
8. Which graph shows the relationship between the pressure and volume of a fixed mass of gas at constant temperature?

9. A small table weighing 40 N stands on four legs, each having an area of $0.001 \text{ m}^{2}$. What is the pressure of the table on the floor?
10. If the pressure exerted on a floor by a box is 200 kPa, find the weight of the box, given that the bottom of the box has a contact area of 20 $cm^{2}$.

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
