State Pascal's law.
Advertisements
उत्तर १
Pascal's law states that pressure applied to an enclosed liquid, is transmitted equally to every part of the liquid or in other words when pressure is applied at a point in a confined fluid, it is transmitted undiminished and equally in all directions throughout the liquid.
उत्तर २
The pressure applied at any point of a liquid at rest, in a closed system, will be distributed equally through all regions of the liquid.
