If the gauge pressure at a point well inside a liquid of density \(\rho\) in a tank is \(p\), then the depth of the point from the surface of the liquid is (atmospheric pressure is P)

If a coin at the bottom of a lake appears to be at a depth of $6,m$, then the gauge pressure on the coin in pascal is ($\mu$ of water = $\frac{4}{3}$)

In a liquid medium, if the depth increases, the pressure at that place ________.

$P_a$ is atmospheric pressure and P is absolute pressure at depth h. The gauge pressure at depth h is:

The total pressure \(P\) inside an air bubble of radius \(r\) at a depth \(h\) below the surface of liquid of density \(\rho\) is (T = surface tension of liquid, \(P_0\) = atmospheric pressure)

What is the speed of water flowing through a hole located at a depth \(h\) from the surface of water in a tank?

What is the work done to stretch a string?

The density of kerosene is \(800\ \text{kg m}^{-3}\). Its relative density is

A body P floats in water with half its volume immersed. Another body Q floats in a liquid of density $\frac{3}{4}$ of the density of water with two-third of the volume immersed. The ratio of density of P to that of Q is

A boy can reduce the pressure in his lungs to 750 mm of mercury. Using a straw he can drink water from a glass upto the maximum depth of (atmospheric pressure = 760 mm of mercury; density of mercury = \(13.6 \text{ gcm}^{-3}\))
