No he wont lose a mark. He will probably get away wih full. They arent so strictyou should have written in 3 sig. figures

it shuld be from alpha or beta becaz gamma radiations are followed by beta or gammaAlpha particle is a helium nucleus, mass 4u, charge 2p, and helium atom was released and it was isotope of helium atom, Since Gamma has mass 0u and 0p, so for the element to be an isotope, my logic says it should be gamma, and beta has a range of energies???
Still can u pleaz post ur reasoning behind ur desicions ??
in the graphs of polymers what kind of graph did u guys draw. In the crystalline one the graph was ductile or brittle?
Truth said....the concepts were new...i'll stick to 50-50 though n hope for good gradesHello All
I hope you guys are discussing paper Paper 22 here I meant varient 2
Mine paper went pretty well expecting 50/60
The paper was tough compared to previous past papers !!
Many candidates found it difficult.
Some questions were very tricky and new concept wise like the radioactivity last part and the p.d between C and D.
Expected Grdae threshold relatively Low
A (35-36 )
i did just like you except i did 0.16-0.06 = 0.1 which gave me the extensionConstant was 25? Extension was 0.06+0.16
many wrote alpha .. no ones surei wrote the radiation alpha radiation. Its wrong right?
btw was it inelastic and that the kinetic energy was not conserved ?
what about the change of energies acting on the mass?
it can be inelastic due to speed before not equal to after.... or kinetic before not equall to after the collision .. .i wrote the secnd one though .. what about you? and what about the radiation one ? what did you write ? alpha?
i
i wrote its inelastic and that ke is not conserved, and for the radiation i wrote alpha , no one really knows whats the right answer honestly so many people wrote alpha or gamma, btw how many marks was the electricity and what did u write for the first part ... I1 = 12 +13? i think thats wrong though
lol i left the reasoning blank it was something so new , but overall how many marks did the electricity question have?and what is your reasoning for writing alpha or gamma? whichever you wrote?
electricity what part? of question?
Kirchhoff one i dont remember what i wrote if you remember the diagram.. i might recall
lol i left the reasoning blank it was something so new , but overall how many marks did the electricity question have?
