66640 Pa pressure is exerted by 0.50 m vertical column of a liquid. If g = 9.8 Nkg−1, calculate the density of the liquid.
What is the use of altimeter?
What are the factors on which the pressure of a liquid depends?
State Pascal's law.
Hydraulic lift works under the principle of _______.
State Pascal’s law.
Assertion: Pascal’s law is the working principle of a hydraulic lift.
Reason: Pressure is thrust per unit area.
Consider a water tank shown in the figure. It has one wall at x = L and can be taken to be very wide in the z direction. When filled with a liquid of surface tension S and density ρ, the liquid surface makes angle θ(θ << 1) with the x-axis at x = L. If y(x) is the height of the surface then the equation for y(x) is:
(take θ(x) = sin θ(x) = tan θ(x) = `dy/dx`, g is the acceleration due to gravity)
