A soap bubble of radius `1//sqrtpi "cm"` is expanded to radius `2//sqrtpi "cm".` Calculate the work done. Surface tension of soap solution `=30 "dyne"" "cm^(-1).`

A soap bubble is blown from a radius of 1 cm to 2 cm. Calculate the work done in doing so, if the surface tension of the soap solution is 42 dyne/cm.

A soap bubble of radius (1)/( sqrt(pi) cm is expanded to double its radius. If the surface tension is 30 dynes/cm, the work done is

A soap bubble is blown to a radius of 3 cm. if it is to be further blown to a radius of 4 cm what is the work done? (surface tension of soap solution =3.06xx10^(-2)Nm^(-1))

A soap bubble of radius 12 cm is blown. Surface tension of soap solution is 30 dyne /cm . Calculate the work done in blowing the soap bubble.
