Question 2 :
In terms of physics, which of the following are considered as fluids?<br>

Question 3 :
When a plane moves along the runway, the air above the wing speeds up more,So the pressure<br>

Question 6 :
A cylinder contains $10$kg of gas at a pressure of $10^7$N $m^{-2}$. The quantity of gas taken out of the cylinder, if final pressure is $2.5\times 10^6$N $m^{-2}$ is?

Question 7 :
Assertion: The force exerted by the fluid is due to the collisions of molecules with their surroundings. Reason: The normal force exerted by the fluid particles on the walls of the container results pressure.

Question 8 :
What is the mass of $2$ litres of nitrogen at $22.4$ atmospheric pressure and $273\ K$

Question 9 :
Water is flowing through a long horizontal tube. Let $P_{A}$ and $P_{B}$ be the pressures at two profits $A$ and $B$ of the tube.

Question 10 :
When the pressure of water is increased, the boiling temperature of water as compared to $100^oC$ will be :

Question 11 :
There are two round tables in the physics classroom: one with the radius of $50\ cm$, the other with a radius of $150\ cm$. What is the relationship between the two forces applied on the tabletops by the atmospheric pressure? then value of $\dfrac{F_1 }{F_2} $ is:

Question 12 :
Consider the equations $P = \displaystyle \lim_{\triangle S\rightarrow 0} \dfrac {F}{\triangle S}$ and $P_{1} - P_{2} = \rho gz$.<br>In an elevator accelerating upward.

Question 13 :
A cube of Ice is floating in water. The fraction of its length lie outside the water is (sp. Gravity of Ice $= 0.96$)

Question 14 :
A right angled tube is fixed horizontally on a horizontal surface and an ideal liquid of density p is flowing into the tube at the rate of $Q = 4 m^3/s$ Cross sectional area of the tube at intake and outlet positions are $A = 2 m^2$ and $S = 1 m^2$ respectively. The magnitude of net force exerted by liquid on the tube is (Given that the value of atmospheric pressure $P_o = 4p N/m^2$)

Question 15 :
What is a pressure on the smaller piston if both the pistons are at same horizontal level? (Take $g=10m$ ${s}^{-2}$)
