YES its rite

guys i wrote A for the diode thing.... is it right ????

for the diode thing in paper 32 i wrote a
but ppl i did a huge mistake in da kinetic energy thingy i wrote mv2 but i forgot to square da value so i got 45000 alll calculations i did were rytt but bcoz of da first value i got all othr values wrong n da last one i still got 1:2 bcoz u get 1.5 so will i loose complete ten marks ny idea how many marks can i get for da question
pls repllyy

if you got the first kinetic energy value wrong, using the wrong formula, youll lose 3 marks, if you used the wrong value correctly to find 10% and all..you can get those 3 marks..the half mass, was independant of everything...and about the last q you had to find the kinetic energy again..if you used the wrong formula again, youll lose 3 marks too..but if you used the formula right, you might just get those too..

i wrote everything correct i jus didnt square it in ma calculator so all da values are affected
--- End quote ---
dont worry u will be penalized onlyonce if u have shown da working and ur method is correct!!!
