Must have been pree hard if you are having mixed feelings, Mr Über Nerd

Any big mark value qs? Ifso, what on?

there was a 6 marker on uses of ac and dc generators and why transformers are required

Nah our option part was replaced with very detailed questions on focus areas 1 and 2. Which I hardly knew.

Plus the fact I practically winged it off past knowledge lol + last night note reading.

There was a six marker as mentioned above, and that's the highest.

 

[iBibah]

ohh, i don't remember the options for that one haha, do you? if you say them I may remember the q.

12 was the one with a graph and you had to find theta (force vs current i think)

39 degrees ?

 

[iBibah]

39 degrees ?

I have a feeling its wrong though

 

[Siddy123]

39 degrees ?

I got this... so it's probably wrong..
soz brahs thats one mark off for yu
99 it is

i ended up with sin inverse of like 6205 or something... lol i just took a guess

Yeh same !!! Got 6000 and something, so I just subbed all of them in with 4a and I got 10 N with 39

I kept getting 625 lol... Took a guess and put 29 degrees

haha why 4a?

 

[iBibah]

haha why 4a?

4A i meant. I used 4 for the amps (in the equation) and then tested each angle tosee which gave 10 N (which corresponded to 4A on the graph).

oh so smart.. lol i hope i chucked in a guess (cant remember), if not ffs LOL

Was torque diagram like an m shaped?

625

62500

either way theyre both greater than 1 lol, hence the trig won't work ;/

m shape? you mean the whole thing was above the x axis?

 

[AnimeX]

yeah, it was kinda of a DC current* graph right?

 

[Hypem]

I did something like that
Just realised I didn't even label the graph, ugh..

 

[labousaleh]

In the last minute while trying to do 12 i realised that force was written in mN on the y axis....... still didn't get it

 

[MATHmaster]

I thought the paper was pretty good
For the torque diagram I got an upside down m because I thought it went anticlockwise, hence the direction would change
oh and I missed an easy 2 marks on the photoelectric effect... sigh

What did everyone get for the projectile question: the range of the projectile?

 

[NFmusic1995]

was the projectile motion question angle 20 degrees, i had a feeling u ahd to 90 - 20 degrees, but just stuck with 20 degrees

also the multiple choice where u had to say the strongest charge between the 2 proximities , the GPE question and even rotating one (and u had to say if its in position A or O or something)

wat u guys get

 

[MATHmaster]

My answer was D for that
I matched the position of the coil with the emf so it was the last one (I think). Q

 

[NFmusic1995]

It was either A or B because theta was 90 degrees... but one was up and the other was negative
