how did you calculate alpha from the graph

You had to realise that UV has a higher frequency therefore a higher energy therefore the biggest gap

For this question did we not have to calculate the frequency of each and then the one with X10^14 Hz is UV

what did everyone get for the diameter of the wire (the question that contained a zero error)

0.51 (the reading plus 0.07)

how did you calculate alpha from the graph

use 2 points to calculate the gradient (beta)

then sub a point on the line into the equation with the gradient and rearrange to give alpha

can someone please tell me why Q9 should be crossed out and what question it was anyway was it the antiproton one???? i wasn't told to cross it out?

yeah that one

something was wrong with the wording

What did everyone got for last quetion? I got 1.5 ish, pretty sure its correct

did anyone get f/square root 2 for the a mcq

ye i did too, (alot of people in my class got the same)

did anyone cross out q9, but still did it incase you heard invigilator wrong?

for the question where you had to plot two points and draw a line of best fit, did anyone draw a curve?!!!???

I wrote that assuming 365 days in a year, the number they gave us divided by (365*24) and that equals 114W

might as well cross out most of the multiple questions as well

It wasn't the antiproton one though?? It was the one beneath it with the kaon and the pion... :s-smilie:

Has anyone made an unofficial markscheme before I forget my answers pls?? :biggrin:

Also, waiting on the hitler reacts :u:

Is that the one which was falling?
Because if it was then it was definitely D because if an object falls then acceleration is always 9.8

You are correct however the acceleration of an object is only g if air resistance is negligible the graph showed the change in velocity decreasing so acceleration was decreasing.

Hey man, I did exactly that, but I left the gradient in fraction form. My teacher said ''no fractions in Physics'' lol so i don't know. Man, that was like a c1-c2 question.

Yo, you worked out hours, when Power is energy transferred per second. So I did divided by (365x24x60x60) but I'm not sure now. Is energy also written as kWh?

Does kWh=J or does it =kJ
