1.Two spherical soap bubbles of radii aaa and bbb in vacuum coalesce under isothermal conditions. The resulting bubble has a radius given bya.(a+b)/2(a+b)/2(a+b)/2b.ab/(a+b)ab/(a+b)ab/(a+b)c.a2+b2\sqrt{a^2 + b^2}a2+b2d.a+ba + ba+bLogin to continueOnly logged in users canattempt or see the solution.
