In solids, interatomic forces are
A man is sitting in a boat which is floating in pond. If the man drinks some water from the pond, the level of water in the pond will
Δι=T×ιA×Y=TY×ιA Hence,TYis constant. Therefore,Δι=ιA ιAis largest in the first case.
Water is flowing through a horizontal pipe in streamline flow. At the narrowest part of the pipe
An egg when placed in ordinary water sinks but floats when placed in brine. This is because
Brine due to its high density exerts an upthrust which can balance the weight of the egg.
The bulk modulus for an incompressible liquid is
Bulk modulus =PressureVolumeStrain
=Pressure0 Bulk modulus =∞[As liquid is uncompressible, ΔV=0]
Pressure at a point inside a liquid does not depend on
If the force on the surface is doubled and area is reduced to half,pressure will
Two pieces of metal when immersedin a liquid have equal upthrust on them; then
Kerosene oil rises up in a wick of a lantern because of
