If the excess pressure inside a soap bubble is balanced by oil column of height 2 mm then the surface tension of soap solution will be 

The quadratic equation whose roots are I and m where is

Two bubbles A and B (A>B) are joined through a narrow tube than,

Direct substitution can sometimes be used to calculate the limits for functions involving trigonometric functions.

In capillary pressure below the curved surface at water will be

 is equal to

The substitution rule for calculating limits is a method of finding limits, by simply substituting the value of x with the point at which we want to calculate the limit.

A spherical drop of coater has radius 1 mm if surface tension of context is   difference of pressures betweca inside and outside of the spherical drop is

The substitution rule for calculating limits is a method of finding limits, by simply substituting the value of x with the point at which we want to calculate the limit.

The radii of two soap bubbles are r₁ and r₂. In isothermal conditions two meet together is vacum. Then the radius of the resultant bubble is given by

We can only apply the L’Hospital’s rule if the direct substitution returns an indeterminate form, that means 0 over 0 or 

The excess of pressure inside a soap bubble than that of the other pressure is

We can only apply the L’Hospital’s rule if the direct substitution returns an indeterminate form, that means 0 over 0 or 

Two wires of same diameter of the same material having the length  and 2 If the force  is applied on each, what will be the ratio of the work done in the two wires?

A graph is shown between stress and strain for metals. The part in which Hooke's law holds good is

We can only apply the L’Hospital’s rule if the direct substitution returns an indeterminate form, that means 0 over 0 or
