where are b(ii) and (iii)AsA
please HELP!! explain the following : http://papers.xtremepapers.com/CIE/Cambridge International A and AS Level/Physics (9702)/9702_w10_qp_42.pdf
Q1 b (ii) & (iii)
Q2 b (ii) & (iii)
and Q5 (a) !!
in Q2b (ii)
WorkDone = Pressure x Change in volume
for Q2(iii)
internal energy = (heat supplied) + workdone
for P-Q u find wd in part1
so just add
for Q-R workdone = 0 so U= 720
for R-P
u know sum of all IE are 0
now calc third IE
put in formula IE = q + WD
and get the wd
For 5a
apply flemings left hand rule
u'll get into the plane!!
hope this helps
