Blaise Pascal
Evangelist Torricelli
Robert Brown
Amedeo Avogadro
Mercury Barometer was invented by Evangelist Torricelli in the year 1643. It is a device used to measure atmospheric pressure.
A fluid exerts pressure in all possible directions of a container.
True
False
this is the property of fluid to exert pressure in all directions of a container.
Pressure at a point inside the liquid does not depend upon :
The depth of the point below the surface of the liquid.
The nature of the liquid.
The acceleration due to gravity at that point.
The shape of the container.
Pressure at a point inside the liquid $(P)=hdg$Hence, it depends on the depth of the point below the surface of the liquid the acceleration due to gravity at that point and on the nature of the liquid but not on the shape of the containing liquid.
