State Pascal's law for pressure transmission and explain its significance.
(N/A) Pascal's law states that a change in pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and to the walls of the containing vessel.
Significance:
$1$. It forms the fundamental principle behind hydraulic systems,such as hydraulic lifts,hydraulic brakes,and hydraulic jacks.
$2$. It allows for the multiplication of force,where a small input force applied to a small area can result in a much larger output force on a larger area,as defined by the relation $F_2 = F_1 \times (A_2 / A_1)$.
