Physics Unit 4 Exam discussion

[homghomg1]

hey for the question it says determine the work fn and h i used the threshold freq (3E14)and then determined the h and W..
would this be correct???

well the formula is W = hf₀
so you can't work out both just by using that formula after reading the value of f₀, you'd have to use the graph in some other way also
I think you could work out the h for that experiment by evaluating the gradient of the graph, then, using the h you worked out, you could find W using W = hf₀
But I would still prefer to just find W by reading the y-intercept
I guess you could also do it the other way around. Find W by reading y-intercept, then work out h using the formula h = W/f₀

lol i mark my one, i got everything right,but i just worry may lose mark on explaining question, im quite lucky, every single explianing question is on my cheat sheet^^, i worry i write too much for each explianing question, i think what i wrote is quite important point to the question but i wrote very detail, u guys think i will lose mark for writing too much?

what kind of study score would i get for physics?

90/90 in midyear exam
86-90/90 on end of year depending on explain questions
94/100 unit 3 SACs
91/100 unit 4 SACs
ranked about 3-5th on SACs out of 3 classes of about 20 students each

[ayaz]

what scores would you need to get a study score of 35 raw???

[THem]

I think most ppl who took TT's cheat sheet would of added in some of their own stuff. Like, I just used bits and pieces

you're kidding right?

you're kidding right?

of course not, why would i ,,,lol what do u think abt it?

lol i will shit myself if i ace this exam, I have never aced an end of year exam

You aced it for sure. Just like how you ace every single SACs you pr0 kent.

actually you could, because all the extra things you said could contradict you main explanation hence you will get marks taken off. Im guessing.

It depends on the strength of your cohort. Maybe 47+?

yeah well you will ace it for sure, just like how you ace (pretty much) every single EXAM :p

lol, 49 or 50

[almostatrap]

wouldn't 50 be reserved for those who got full marks on both, there'd be a few.
