MAY13 Physics SL Paper 2 TZ2 Discussion

[rc_1995]

I found it pretty okay.

The only tough part in section A for me was the first question (part b), I proved the used the theory that the halflife would be equal to prove that the function was an exponential in the form of V=V0e^-kt.

For the graph of the kinematics section, it was increasing from 0 to t, constant from t1 to t2 and dropped to 0 at t2. The free body diagram was just a gift.

And in section B, I did question B1 on nuclear and thermal which I found to be the easiest amongst all 3. Especially the binding energy question. And for thermal, I used the delta heat lost being equal to (power x time (heat supplied) - mc delta t (heat absorbed by water) ) / time taken (120 s)

So how was it guys?

I have Physics HL. P1 was fine, P2 was pretty brutal. Not bad, but definitely a lot harder than previous years. I am kinda scared of Math HL...

Same here man. Section B is what I'm worried about.

I had TZ1 paper 2 and its been 24 hours i hope since i wrote it like yesterday.....mine was brutal but paper 1 was THE easiest exam ive ever written.

was it supposed to be a straight line from t=0 to t=1?

I've answered all the questions from section A and B1 I really dont know if all the answers were right haha but the fact that I've had answered all the questions makes me happy
