hello everyone. Im writing a project on the topic“ Solution of
Nonlinear partial differential equation using charpits methods”
curently writing chapter 2 but I′m a little bit confused about what ih
should include in my theoretical framework. Any ideas?
Why is surface tension formula divided by 2L
that is, surface tension = (F/(2L))
why divided by 2L.
Where did the 2 come from?
Example.
Calculate the force required to lift a needle
4cm long off the surface of water, if surface
tension of water is 7.3 × 10^(−4) Nm^(− 1)
Why is the formula surface tension = (F/(2L))
why not surface tension = (F/L)
1. Find the length of each of the following
(a) {x : −3 < x < 7}
(b) {x : 2 ≤ x ≤ 6} ∪ {−3 ≤ x ≤ −1}
(c) {x : −2 ≤ x < 5} ∪ {1 < x ≤ 7}
2. Let I=(a, b). Prove that I is measurable
and m(I) = L(I).
