Answer 1

hope this helps any doubts please comment

Answer 2

Dear Student,

◆ Answer -

M1/M2 = (r1/r2)^3

● Explanation -

Mass of 1st soap bubble is -

M1 = V1 × d

M1 = 4/3 πr1^3 × d

Mass of 2nd soap bubble is -

M2 = V2 × d

M2 = 4/3 πr2^3 × d

Ratio of masses of air in soap bubbles is given by -

M1/M2 = (4/3 πr1^3 × d) / (4/3 πr2^3 × d)

M1/M2 = (r1/r2)^3

Thanks dear. Hope this helps you...
