Question

obtain an expression for surface tension of a liquid depends on mass, pressure and radius.​

Answer 1

Answer:

Select the correct alternative(s) :

a) the amplitude of component waves is 2 mm

b) the amplitude of component waves is 4mm

c) the smallest possible length of string is 0.5 m

d) the smallest possible length of string is 1.0 m

1) a, care correct 2) b, c are correct

3) a, d are correct

Answer 2

It has no component perpendicular to the horizontal surface. As a result, there is no pressure difference between the liquid side and the vapour side. ... Thus, there is always an excess of pressure on the concave side of a curved liquid surface over the pressure on its convex side due to surface tension.
