If the surface tension at the soap-air interface is 0.09 calculate the bubble of 28 mm diameter.

If a bubble is charged, In equilibrium, the force produced due to surface tension is equal to the sum of forces due to excess air pressure inside the bubble and the electrical pressure due to charge

if the pizza is divided equally into 2 equal halves then you would get

πr^2/2

where r is the radius of the pizza.

happy to

pls mark as brainliest

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
