- I need to fix error in schedule. We decided to have exams on Monday, and also to meet in one long segment MW starting at 10 AM.
- Assignment:
- Click here to go up one level and click the three integers ### to get into your private miraheze account. You will be refused until you log in with your wsul### username and your password. Log in and click main page.'
- Add your user name to Wright State University Lake Campus/2017-1/Phy1060. Do this by replacing _username by your username. )
- Open your private wiki account wsul### and click edit. You will see instructions enclosed in the "hide" tags:
<!-- hidden text-->
- replace xxx by your Wikiversity username. This creates a link back to your Wikiversity page
- Fill in PHY1120 as instructed when y
- Create a word document called Enrollment and put it in your dropbox. For now, it should contain only your wsul### (046-056). Also place your noun### password so you won't forget it.
- Paste this into your Wikiversity user account

- , where E electric field is and ΔV is voltage
- if d and E are parallel. Here d is displacement.
The above formula fails if E is not constant, but over a small distance it does work. Replace Δ by d and use calculus. For a distance, r, from a point charge or a spherically charged sphere:
- (I used absolute value signs...don't worry about minus signs because they are too complicated to keep track of)
- You might choose to not learn Special:Permalink/1378605 because it is not likely to be on an MCAT. (It teaches vector algebra)
- Project ideas:
- Neatly solve problems that were not well solved in the answer key
- Pose and solve problems in the book that look appropriate
- Explain something for students. (???)
20 February 2017 (UTC) Is the osmotic force a "pseudo-force"?[edit | edit source]
What is the force that drives the molecules through the membrane? This is a misleading question, because there is no real “force” in the physical sense other than the thermal energies all molecules possess. Osmosis is a consequence of simple statistics: the randomly directed motions of a collection of molecules will cause more to leave a region of high concentration than return to it; the escaping tendency of a substance from a phase increases with its concentration in the phase.
Chem1 General Chemistry Virtual Textbook → solutions → osmotic pressure
The answer is yes and no. Wikipedia does not include osmotic forces in its article on pseudoforces. But search the word pseud in this excerpt] from the Google books search engine. The quote to the right is a good explanation.
