Guys what did you get for the communications question that said time taken to change from ,,,... ( i dont remember the exact question but it was the last part of that question )

I did, everyone found it really hard.
WTF WERE HALF THOSE QUESTIONS.
What did you get for the contrast question? And the capacitor?

i added them since its gotta pass through both capacitor AND muscle???
and also the capacitor has same charge as I * t right

  • That was such a shit exam, seriously its like they gave us an exam in yiur 3rd year of university studying physics, the grade thrsehold should truly be 40 for an A

I did. Did you use the tangent to calcualte the activity of the nucleus in the second to last Q?? I didnt...

i used a tangent

i think it was multiplied, had a similar question in our mocks. but the Io thing confused the hell out of me. and yes, it had the same charge, i think? I'm so unsure about all my answers. why did they give the frequency as 50 though? some people used it to calculate charge, and it kind of made sense.

lol i guess itll hit an early 50 for both
wut was so shitty abt it btw?

there were a bunch of new conceptual questions. there was a particular question no one could solve- sand was placed on an oscillator of s.h.m and then the amplitude was slowly increased till it slid off. they asked to find the new amplitude. everyone was like lolwot

the first part said in ONE second, idk why would we use it in that part and i was thinking we should use it but it only asked for ONE time charge up why would I multiply by 50? so like did the whole batch find it hard?

Do you think you get any marks for using the exponential curve equation and given the half life?

I multiplied too. I divided the total charge by 50.
