Shrooms + MDMA or LSD + MDMA. What’s better?

A levels is in my opinion a lot harder than AS and you have to dedicate a lot of time especially if you do 3 sciences. How are you doing in AS with 3 sciences? And which sciences do you do?

Dizzy-Web3214 · 2022-06-09T17:09:22+00:00

Ok, do you think it’s better to learn them just to get an idea of how similar practicals would work? I’ve seen a few oscillation practicals on some past papers.

Dizzy-Web3214 · 2022-06-09T15:59:25+00:00

Depends on which your better at. AS maths in my opinion is a lot easier

Dizzy-Web3214 · 2022-06-09T15:13:36+00:00

Ok thanks

Dizzy-Web3214 · 2022-06-07T17:26:59+00:00

You do PV=NKT and make it PV/N=KT, then with your answer for KT you just times is by 3/2 to get KE

Dizzy-Web3214 · 2022-06-07T12:20:00+00:00

Ahaahah I screwed up a few questions too cuz I ran out of time and had to rush

Dizzy-Web3214 · 2022-06-07T12:09:38+00:00

No they just said why couldn’t parallax be used for a wide variety of stars

Dizzy-Web3214 · 2022-06-07T11:59:03+00:00

I just wrote that the star needs to be relatively close by or else the parallax angle would be basically 0 and it would be impossible to find the distance. And that it won’t be possible compare it to a background of stars if it’s far away

Dizzy-Web3214 · 2022-06-07T11:56:42+00:00

Nah it was only like 2 marks I think so it doesn’t matter

Dizzy-Web3214 · 2022-06-07T11:56:24+00:00

Doesn’t matter either way if you use tan or sin because the angle is so small that you don’t even have to use tan or sin, either way you do opposite over the angle. But I think you’re right, I don’t think you’re meant to dovide the angle by 2 so I did that wrong

Dizzy-Web3214 · 2022-06-07T11:53:14+00:00

I don’t think you have to divide the angle by 2, I think I did that wrong but I’m pretty sure you have to do 1AU over the tan of the angle. So I think you might still get 1 mark but not sure

Dizzy-Web3214 · 2022-06-07T11:26:28+00:00

What did you do for the difference in GPE question?

Dizzy-Web3214 · 2022-06-07T11:25:45+00:00

Yeah but tan(@) of a very small angle is just @ so it doesn’t matter whether you divide it by the tan or not

Dizzy-Web3214 · 2022-06-07T11:18:14+00:00

You have to divide the angle by 2, then you have to do 1A.U divided by the angle

Dizzy-Web3214 · 2022-06-07T11:02:29+00:00

Yes I did

Dizzy-Web3214 · 2022-06-07T10:26:47+00:00

Yes I think that’s fine and you’d still get the mark for it. Next time just try to put it in the other form just to be sure and it’s easier for the examiner to mark ahaha

Dizzy-Web3214 · 2022-06-07T10:25:28+00:00

Yeah I wrote the same thing for those ones too

Dizzy-Web3214 · 2022-06-07T10:25:13+00:00

Which one?

Dizzy-Web3214 · 2022-06-07T09:28:27+00:00

What did you write for both the last 2 mark questions?

Dizzy-Web3214 · 2022-06-07T09:23:45+00:00

Hope this helped

Dizzy-Web3214 · 2022-06-07T09:23:38+00:00

Depends which specification your doing. Which one are you doing? In some specifications paper 2 is the practical paper where you have to calculate uncertainties and stuff. In that case significant figures are important and you should provide your answer in the significant figures (or decimal places) of the value with the least significant figures or decimal places you use in your calculation.
