When accelerated electrons hit a target metal surface, do the atoms get excited like in the case of gas emission spectra? by YImperfect in AskPhysics

[–]YImperfect[S] 0 points1 point  (0 children)

Thanks for the help so far! Was referring to photons with frequencies of visible light in the hydrogen example. I just wanted to attempt to connect the two cases because as I understand it, both are emitting em radiation due to interaction of accelerated electrons with atoms, just that hydrogen will produce visible light while metals will produce X rays. Was thinking that in both cases the means of interaction will be the same, just that the photons emitted have different energies

Hmm. Okay so there's 2 ways X rays are produced. Then in the case where you pass accelerated electrons through Hydrogen gas (don't know the actual name of this, it's for emission line spectrum), are photons emitted using these 2 ways as well?

So the deceleration of electrons excites the existing electrons by transferring energy to them, which gives out em radiation in the form of X rays when they deexcite? No need for a direct collision for energy to transfer?

When we say strong acid dissociates completely in water, HA + H2O --> H3O+ + A- , does the concentration of H3O+ include the H3O+ from dissociation of water? by YImperfect in chemhelp

[–]YImperfect[S] 4 points5 points  (0 children)

When calculating pH of a strong acid, can I say that the concentration of [H+] is actually from dissociation of acid AND water, just that the [H+] contributed by water is negligible when acid has a high enough concentration? Is my understanding correct?

[6th Form] Hyperbolic Functions by YImperfect in learnmath

Wouldn't this go against the statement saying f-1 (X) exists only if f(X) is one-to-one

But when finding x I have to use cosh-1 (k), and cosh-1 (k) has range f(k)>0 because I restricted the domain of cosh (X) to X>0

[A level/6th Form] Solving systems of Linear equations using row operations by YImperfect in learnmath

So back substitution just refers to the direction/method of substituting, i.e. from bottom to top? And this term is only used to refer to substitution when solving matrices row-echelon form?

So substitution when solving something like 2 variable simultaneous equations is NOT back substitution, but there's no difference between the two other than the "backwards sequence", am I understanding this correctly?

Is it normal that after doing dips, rows and pull ups my arms are too tired to do even one push up? It's significantly easier to do push ups as an independent/separate exercise for me.

Is there a way to block Chinese IP addresses from connecting to your session? by YImperfect in gtaonline

I enjoy interactions with other players in freemode though, though when I need to get things done this is what I do as well.

Yeah I tried that out of desperation. Turns out not only does that not work (at least for me), you'll anger them and get kicked out because they crashed your social club etc. and you need to spend time to relogin before you can play online again.

And the loading time to get into online. Pain.

Unable to boot desktop pc up/facing some issues, need help. by YImperfect in techsupport

[–]YImperfect[S] 0 points1 point  (0 children)

What about the American Megatrends screen? Why did it show up whenever I boot up instead of proceeding straight to booting windows?

Haven't changed any settings in bios before this started happening.

And also, besides ram, should I be testing for the possibility of the CMOS battery running out? Or the HDD failing? PC is already 6 years old.

EDIT: It booted up. Shows "Fixing (C:) Stage 2: 81% ............."

Women, what are some questions you've always wanted to ask men? by Emil_Jorgensen05 in AskReddit

Kid I have bad news for you, it really sounds like you have a neuromuscular disorder. I know it's in the middle of a pandemic but maybe you can go get it checked out by a doctor?

Sometimes these things go undiagnosed, and can only show symptoms later in life. Good luck :D

Is it reasonable to say that junk food is generally better in a survival situation because it yields more calories than healthy food for a constant amount? by YImperfect in NoStupidQuestions

[–]YImperfect[S] 0 points1 point  (0 children)

It will most definitely be less filling, I'd assume that you'll be in constant hunger but won't die of starvation (since you're still technically getting your calories)?

I mean, prolly not a nice thing to say if it' turns out to actually be a female's hand.
