The limbs of a `U`-tube are lowerd into beakes `A` and `B`. A contains water and `B` some other liquid. Density of water is `1g//cm^(3)` . Some air is pumped out from `C` and then this end is closed, as a result of this liquids rise by `10cm` and `12cm` respectively, on the left and right side. which of the following is/are correct?

A spray gun is shown in the figure where a piston pushes air out of a nozzle. A thin tube of uniform cross section is connected to the nozzle. The other end of the tube is in a small liquid container. As the piston pushes air through the nozzle, the liquid from the container rises into the nozzle and is sprayed out. For the spray gun shown, the radii of the piston and the nozzle are 20mm and 1mm respectively. The upper end of the container is open to the atmosphere. If the piston is pushed at a speed of 5mms^-1 , the air comes out of the nozzle with a speed of

For the spray gun shown, the radii of the piston and the nozzle are 20mm and 1mm respectively. The upper end of the container is open to the atmosphere. If the density of air is rho_a , and that of the liquid rho_l , then for a given piston speed the rate (volume per unit time) at which the liquid is sprayed will be proportional to

In a U-tube diamter of two limbs are 0.5 cm and 1 cm respectively and tube has filled with water (T=72"dyne"//cm ) then liquid level difference between two limbs will be

When 100 drops of a liquid P is added into a liquid Q the volume of the liquid in the container which is initially filled with liquid Q doubled. Determined density of the mixture if density of the liquids P and Q are 1.5 g cm ^(-3) and 1.3 g cm^(-3), respectively

In the arrangement shown in figure a viscous liquid whose density is rho=1.0g//cm^3 flows along a tube out of a wide tank A. Find the velocity of the liquid flow, if h_1=10cm , h_2=20cm , and h_3=35cm . All the distances l are equal.

Water stands at a height of 100 cm in a vessel whose side walls are vertical. A B and C are holes at height 80 cm, 50 cm, and 20 cm respectively from the bottom of the vessel. The correct system of flowing out is:

At 100^(@)C and 1 atm, if the density of the liquid water is 1.0 g cm^(-3) and that of water vapour is 0.0006 g cm^(-3) , then the volume occupied by water molecules in 1 L steam at this temperature is

At 100^(@)C and 1 atm , if the density of the liquid water is 1.0 g cm^(-3) and that of water vapour is 0.0006 g cm^(-3) , then the volume occupied by water molecules in 1 L of steam at this temperature is
