If a soap bubble of radius 3 cm coalesce with another soap bubble of radius 4 cm under isothermal conditions the radius of the redultant bubble formed is in cm

If a soap bubble of radius 3 cm coalesce under isothermal conditions with another soup bubble of radius 4 cm, find the radius of the big soap bubble so formed.

A soap bubble of radius 6 cm and another bubble of 8 cm coalesce under isothermal xonditions in vacuum. The radius of the new bubble is

Two soap bubbles of radii 1 mm and 2 mm merge isothermally . Then radius of the new bubble formed would be

Two soap bubbles one of radius 3cm and other of radius 4cm each coaless in vacuum under isothermal conditons. Calculate the radius of the bubble formed ?

A soap bubble in vacuum has a radius of 3 cm and another soap bubble in vacuum has a radius of 4 cm . If the two bubbles coalesce under isothermal conditions then the radius of the new bubble is :
