*edit*


when pH in environment is lower than pKa, u will push the equilibrium towards reactant though
HA <--> H+ + A-

You're right, form AG is the most popular one! Wow...
NYC here

Boston here

others?

I dont understand that amp and phase one at all. .....

I hope we're both right then. And wasn't the velocity and acceleration simply like sin and cos waves?

.....Yeah, concave=inverted, real and convex=inverted, virtual. Sorry, can't really remember the specific qs.

....Yeah, concave=inverted, real and convex=inverted, virtual. Sorry, can't really remember the specific qs.

no.

concave lenses always produce erect virtual images.

convex lenses can produce erect virtual images or inverted real images.

 

[VoiceofReason]

yeah sorry my mistake i get the names confused

 

[RB69]

no.

concave lenses always produce erect virtual images.

convex lenses can produce erect virtual images or inverted real images.

Actually, convex lens can only produce real inverted images only (at least that's what I remember from the Princeton's PS book).

What happens when the object is located in front of the focal point?!?

i remember from the EK bpok that in that case it would be upright and virtual

 

[tennisguy896]

not if they are within the focal length

but then the question's was ....

Yep, nevermind, I have the same answer as you. I can only describe it right when I draw the lens.

Ah, my bad. Yes that's correct!

Things about convex (converging) lenses:

Image will be virtual and erect if the object is between 0 and f.

Image will be real and inverted if the object is located further than f.

Image will be larger if the object is between 0 and 2f.
Image will be the same size if the object is located at 2f.
Image will be smaller if the object is located further than 2f.

ok i get it now, t=0 thats initial displacementso stupid of me. all my books say instanteous displacement, damn the amcc for the million time

Unless they gave us a unique equation, the only one I know of is the one above where roe=resistivity. Resistance is proportional to the resistivity of a specific material.

No thats definitely the equation you were supposed to use i just didnt see what i calculated among the answers.
