Explanation:
The pressure of a liquid is the rate of the force applied by the liquid on a surface per unit area of the surface.
i.e P =
where P is the pressure, F is the force and A is the area.
The depth of the liquid determines its pressure at a definite lower point. As the pressure of a liquid at the bottom of a its container is greater than the pressure at the top of the liquid.
Thus,
P = σhg
where P is the pressure, σ is the density of the liquid, h is the height and g is the force of gravity.
It is measured in Pascals or N.
The pressure of liquid has a lot of applications, viz: siphon, force pump, lift pump etc.
Answer:
Explanation:
Natural length of the string is given as
length of the string while block is hanging on it
extension in length is given as
now we have strain in the string is given as
similarly we will have cross-sectional area of the string is given as
now the stress in the string is given as
Now Young's Modulus is given as
