Test 2 Alveoli question

Postby ariana_apopei1K » Sun Nov 04, 2018 6:55 pm

Hi everyone!
I would love some quick clarification on question 1 from test 2: anytime we are given the diameter in this type of question we substitute it directly in for delta x? As in no manipulations or using formulas, the diameter covers the potential position for the molecule?
Thanks and good luck tomorrow!

Yes the position in question 1 is just the diameter, 2x10^-4 m.

Yes, because in the problem, the electron's position could be anywhere within the alveoli sac (therefore, within the diameter), and could not be outside of it, therefore that is the range or uncertainty of the position (delta x).

Some questions give the radius instead of the diameter, in that case would we multiply the radius by 2?

I think that's correct yeah!
