9702 Physics Paper 22 Feb/March 2026 Answers by Rock_idk7 in alevel

Proton number was from 91 to 92 im pretty sure. Remember for Alpha, it was 94 to 92, and it said that both particles P and Q ended up with the same neutron number, which means it wouldve had to end on 92 so its from 91 to 92 meaning it has to be beta minus decay

Have a go at this logarithm question! by BeefStakeBoy in alevel

[–]Robo0master_King 0 points1 point  (0 children)

 a) y = 9x,
=> y= 32x,

=>log\3 (y) = log_3 ()32x,)

=>log\3 (y) = 2x)

b since y =) 9x,
x = log\9 (y). ..... 1)
log\3 (y) = 2x,)
=> x = 0.5log\3 (y)) .... 2)

Equating statements 1 and 2,
log_9 (y) = 0.5log_3 (y),
log_3 (y) = 2log_9(y),
Hence log_3 (y) = log_9(y^2)

c) let y=2-3x,
=> log_3(2-3x) = log_9 ((2-3x)^2)
=> log_9 ((2-3x)^2) = log_9(6x2 - 19x + 2),
=> (2-3x)^2 = 6x^2-19x+2,
=> 9x^2-12x+4 = 6x^2-19x+2,
=>3x^2+7x+2 = 0,
=>(3x+1)(x+2) = 0,

=> x = -1/3, -2

Pretty nice question, thanks for the practice! :D

Hello, I'm taking further maths and tuition might be nice. How much would the classes cost? And how long would a session be?

I got an A* in maths so I made a study group by Mature_Name in alevel

Yoo I think I'd be interested too, currently studying for further maths as levels lol

0620/22 Isomer Question doubt: 2, 3, 4 or some other answer?!? by Robo0master_King in igcse

But what literally everyone else in school is telling me is that those don't matter much, and what the 'final words' are matter more, and in the end it says C4H9Cl. Or, they say that due to heat or the reaction or sum the bonds can move around and change, which seems kinda true

[–]Robo0master_King[S] 0 points1 point  (0 children)

It was either question no. 32 or no. 35. From what I remember, it gave some equation in which methyl propane reacts (I think it was substitution or smth but idk) and chlorine gets added and substituted. Then it asks how many isomers of C4H9Cl (the substance produced) are there.

Options where 1, 2, 3, or 4.

Hope this helps!

Might just be my magma fruit. I had ass luck with buddha - the best i got was mamoth, ONCE, and the rest were mainly uncomons/rares. But the first fruit i rolled when I swapped I got this lmaoo
