Question

In the formula N =- D { n2- n1 / x2 - x1 } where D = diffusion coefficient n1 and n2 is number of molecules in unit volume along x1 and x2 which represents distances and N is number of molecules passing through per unit area per unit time calculate dimensions of D​

Answer 1

Answer:

kya brooooooooooooo matlab ki khuch bhi

Answer 2

Answer:

Explanation:

You solve this like any other equation. According to the text you have the following units.

[] means dimension

[n] = [L]^(-2)* [T]^(-1) [n2-n1] = [L]^(-3) [x2-x1] = [L]

[n] = [d]*[n2-n1]/[x2-x1]

put the above values in:

[L]^(-2)* [T]^(-1) = [d] * [L]^(-3) / [L]

[d] = [L]^(-2)* [T]^(-1) * [L] / [L]^(-3)

[d] = [L]^(-2+1+3) * [T]^(-1)

[d] = [L]^(2) * [T]^(-1)
