give the pascles law.....
Answers
Answer:
Pascal's law states that
"If the pressure in a liquid is changed at a particular point, the change is transmitted to the entire liquid without being diminished in magnitude"
Explanation:
We know the pressure difference between two points in a liquid is given by 'ρ*g*h', where ρ is the density of the liquid, g is the acceleration due to gravity, and h is the vertical distance between the two points. We have to keep in mind that ρ and g are constant (ρ for a liquid). So clearly the pressure difference dP depends only on the vertical height between the two points. Suppose by some means the pressure is increased at a point in the liquid, then the pressure in all other points also increase in the same amount to keep the pressure difference constant.
