did anyone use E=hf for working out the frequency, i multiplied the work function by 1.6*10-19 and divided by planks constant, who else used my method and i said its ultraviolet range

i think we are right cause using a simple equation was used in the area of gauge resistance question i mean it doesnt make sense to give us 2 questions depending on equations

do u remember what was the mark for the calculation?
I used that and got everything right but then i crossed out uv and wrote x-ray I think they MIGHT accept either though because they are fairly close and we're not supposed to remember the EXACT wavelengths. Who knows, maybe MS will be generous
Yesss! Do you think we were right though? :S Every one else seems to think resistance increased, which seems like an obvious answer because of less current.
That's true! Sounds good. Also, how did you find the polarising questions? I thought they were fairly easy but they all seemed to be asking the same thing lol
,
hopefully we are right, i think the grade boundries are going to 57/59 for an A, unless people did bad on the electricity questions
I think the grade boundaries will be 55 for an A. It's a Unit 2 Physics paper after all, so they can't make it too high. And besides, no one from the exam hall said it was easy, many thought it was 'decent'.
55 that seems kinda of low 58-59 is more like it
Yeah maybe you're right. What do you think full UMS will be? I haven't seen the questions yet but I don't think I dropped more than 10 marks maybe. Inshallah
Nope it doesn't. SorryThe drift velocity of the electron was V/4 guys because as length increases the number of charge carriers also increases!
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
