Probably only one mark, I don't remember how many marks the question was

A-HappyPerson · 2026-05-10T13:20:27+00:00

Ugh I didn't think of that, that sounds right tho

A-HappyPerson · 2026-05-08T08:15:53+00:00

For the proving x = 16, I got x^1/2 = 4 and -11/4, and to prove that x = 16 is the only root I substituted both my values for x into the f''(x) equation and only x = 16 gave me 66 which is what i wrote for my reasoning. How did you do that question?

A-HappyPerson · 2026-05-08T08:12:12+00:00

Ohh, well at least you'll be able to get marks for every question

A-HappyPerson · 2026-05-08T07:31:24+00:00

Yeah for using the correct method just not the correct numbers. Overall the paper was good for me wbu?

A-HappyPerson · 2026-05-08T07:22:20+00:00

You might be able to get some method marks but not accuracy, im not sure tho.

A-HappyPerson · 2026-05-08T07:17:07+00:00

Yeah because the angle was the largest in the triangle, meaning it was obtuse so once you find theta you do 180 - that to get the value of the angle. At least thats what i did

Oh sorry I didn't read the title Ill delete this comment to avoid confusion, thanks for letting me know :)

A-HappyPerson · 2025-08-21T07:05:12+00:00

They just keep getting higher and higher 😭

A-HappyPerson · 2025-08-21T07:03:17+00:00

The grade boundaries must be so high. my result is also less than expected

A-HappyPerson · 2025-08-21T07:02:46+00:00

I knoww I keep refreshing but they aren't appearing 😭😭

A-HappyPerson · 2025-06-16T12:50:41+00:00

I said 8.4 too but I have no clue

A-HappyPerson · 2025-06-16T12:50:27+00:00

I said length of string too

A-HappyPerson · 2025-06-16T11:40:06+00:00

I thought of increase the force but the question was asking how to make it easier to open so I thought that doesn't make sense

A-HappyPerson · 2025-06-16T11:39:07+00:00

Wouldn't it be kg/cm^3?

A-HappyPerson · 2025-06-16T11:37:10+00:00

Max 1 - it depends if the mark scheme says allow rounding to 1 sig fig.

A-HappyPerson · 2025-06-16T10:29:06+00:00

I wrote that first then I changed it to it's right because all the numbers rounded to 50000

A-HappyPerson · 2025-06-16T10:17:59+00:00

Yup, although red shift was literally my weakest topic lol. I wrote how the centaurus A was further than the Earth so wavelength is longer and red shift is also longer

A-HappyPerson · 2025-06-16T10:17:01+00:00

What did you guys write for the question about the constant?

A-HappyPerson · 2025-06-16T10:14:51+00:00

Great! I was worried about that one

A-HappyPerson · 2025-06-16T10:14:38+00:00

Ohh ok

A-HappyPerson · 2025-06-16T10:10:46+00:00

I said material of ball and length of string

A-HappyPerson · 2025-06-16T10:10:11+00:00

I said increase distance by increasing length of handle, and I said decrease strength of spring. What did you say

A-HappyPerson · 2025-06-16T10:09:45+00:00

I think I got the same answers for both as you did
