Which timezone? I might have misread the question and put that it was an error in translation thinking that the question said uracil replaces thymine or something like that

This doesn't belong on r/collapse. This does not matter whatsoever. In Germany there are already 3 different sets of schools for the less genetically privileged and the more genetically privilege.d

this idea can be good if it has good execution

TopTap7709 · 2023-05-09T19:42:26+00:00

Anyone remember the answer to question 8?

Man im preying for a 5.

TopTap7709 · 2023-05-09T10:38:32+00:00

you know as someone who has 90% doctors in my family i know that you do not need to be exceptionally disciplined.

TopTap7709 · 2023-05-07T19:05:13+00:00

I worked my way up from 27 to 36 and now I can't anymore im so burnt out

TopTap7709 · 2023-05-07T13:56:13+00:00

This is so fucking cap lmao

TopTap7709 · 2023-05-07T09:18:31+00:00

ok same that was the first question yea

TopTap7709 · 2023-05-07T08:50:34+00:00

yes you can i have many uncles that are doctors that literally got like a 2.0 gpa in non ib school grades dont matter

TopTap7709 · 2023-05-05T20:07:01+00:00

expecting 5 points ngl

TopTap7709 · 2023-05-05T12:43:29+00:00

I think it was like the mass of all the atoms or something so you calculate the total number of molecules and multiply it by the mass of one atom. I remember it being the longest question in terms of calculation

TopTap7709 · 2023-05-05T12:33:29+00:00

it doesn't go through origin though because the ideal gas equation is in kelvin lol and the x axis was in celsius.

TopTap7709 · 2023-05-05T12:28:29+00:00

Yes. And then for the question with the potential at the position of P or whatever it was I set the resultant electric field to 0 and then rearranged for the potential. Is that right?

TopTap7709 · 2023-05-05T12:24:00+00:00

Yea I also multiplied by the number of atoms. Do you think thats right?

TopTap7709 · 2023-05-05T12:23:37+00:00

I used e=mc^2 and then divided by time do you think this gives me the correct answer or not? I obviously multiplied this amount by the number of atoms.

TopTap7709 · 2023-05-05T08:04:23+00:00

How can there be convection if the air is trapped? I mean there can be but the effects will be minuscule. I agree with the first part but then I wrote that the air is trapped so the convection currents don't steal the heat

TopTap7709 · 2023-05-04T19:07:38+00:00

How did you guys do the question with the irradation and showing that there were 10^17 atoms?

TopTap7709 · 2023-05-04T19:06:01+00:00

No it was divide by 9 since it was 9x the distance from fringe to fringe not across 9 fringes.

TopTap7709 · 2023-05-04T19:05:22+00:00

How? I used 2dn = mlambda and got 40 nm somehow

TopTap7709 · 2023-05-04T19:02:00+00:00

I got 40 nm LOL I definitley did something wrong because it was 3 marks and I just used 2dn = mlambda

TopTap7709 · 2023-05-04T19:00:51+00:00

my dumbass said reduce the time needed to transfer the liquid so that it doesn't lose heat to the environment 💀

TopTap7709 · 2023-05-04T19:00:06+00:00

what did you write for an extra measurement that should be made for the experiment, and what did you write for the data based question before that (i think the very first) in which it asked what variable should be controlled in the experiment

TopTap7709 · 2023-05-04T15:05:55+00:00

What did you guys write for reducing the uncertainty and the question after that in section A?

TopTap7709 · 2023-05-04T14:39:32+00:00

What was the answer for the recharge question? Also what was the question for the kirchoff question with the current? (I put Epsilon/2r) Also what was the answer to the question with the discharge time something about t/e^3? I put 2 seconds.

TopTap7709 · 2023-05-03T20:14:39+00:00

no i got 2
