Identical wire loops are dipped into liquid a and liquid b, so that a film of liquid forms across the loops (like the bubble solution on a child's bubble blowing wand). the width of each loop is increased slowly and the forces fa and fb needed to make the loops 5% wider are measured.

(a) fa will be greater than fb

(b) fa will be less than fb

(c) fa will be equal to fb

(d) it is impossible to predict whether fa or fb will be greater without more information.

(b) fa will be less than fb

Explanation:

The identical wires loops are dipped into two liquids a and b. The liquid forms across the loop and the width is increased slowly. The forces will make loop wider but fa will be less than fb. When the wire loop is dipped in the liquid the distance in wire loop will increase by 5%.

answer:

a

answer:

the army does care about its soilders sir i think yout getting off on the wrong foot sir you need to respect our country were keeping the peole that want to d harm towards you out. so dont go saying we don't care cause we do
