The density of bubble gum is about 910 kg/m3 . You blow a 6.90-gram wad of gum into a bubble with a measured diameter of 8.70 cm . Assume that all of the gum is in the skin of the bubble. Part A What is the thickness of the bubble?

a) mass of bubble is constant

volume of bubble = 4*3.14*r*r *t

mass of bubble =6.9

mass = V * density

calculating

thickness t = 31.88 mm

b) if diameter is 1/4 of final dia

final dia = 4 * initial dia

then thick ness will be 1/16 times inititial thick ness

t (2) = 1.9929 mm
