Question

a drop of oil of volume 10 raise to the power of minus10m raise to the power of 3 spread out on water to make a circular film of radius 10m, what is the thickness of the film

Answer 1

Pls i dont no, solve the question for me, thank you

Answer 2

The oil film forms a cylinder, so the volume is V = πr^2 h
So, plugging in your numbers,
π * 10^2 * h = 10^-10
h = 10^-12/π
