Figure 3 shows the levels of two liquids A and B after some air has been sucked out of the tubes through the tap. ![]() State Pascal’s principle of transmission of pressure in fluids. what is the pressure at the place in #Nm^-2#? (Density of mercury is 1.36 x 104# kgm^-3#) The reading on a mercury barometer at a place is 700mm. The area of contact of each of the four tyres with the ground is #0.025m^2#. The total weight of a car with passengers is 25, 000N. (Density of water is 1000#kgm^-3# and acceleration due to gravity is 10#ms^-2#) Determine the force on the cork when the tank is filled with water. A hole of area 2.0#cm^2# at the bottom of a tank 2.0m deep is closed with a cork. State the reason why it may not be possible to suck liquid into your mouth using drinking straw on the surface of the moon. State one advantage of fitting wide tyres on a vehicle that moves on earth roads. what would be the height of a column of paraffin in barometer at the same place? The height of the mercury column in a barometer at a place is 64cm. A small nail may pierce an inflated car tyre and remain there without pressure reduction in the tyre. Given that h1 = 8 cm, determine the value of h2. 2 shows a U-tube containing two liquids L1 and L2 of densities 1.8g #cm^-3# and 1.8g #cm^-3# respectively in equilibrium. State what would happen to the flow if the system in Fig.
