    for c ..we cud write the ratio of X to Y as (Y/X)^-1 so it goes as(C-X/X)^-1 =(C/X -X/X)^-1 C/X =l^3 of C/l^3 of X) and X/X =1 u do the subsequent math

    really ..the dotted line conc is in D4 and also in locus questions whre for instance y,<x not y<=x in which they show a dotted line....I get wht u mean by shading the region but since the (for instance) the circle shud be less than 3 cm and the line is the boundary shudn,t we draw tht line...

    tht,s wht I have been trying to say tht the HEIGHT component in the line OP and BA wud be such tht it will be dependant on their length as they both subtend the same angle...so the height of theirs wud differ such tht Height of BA wud be 1.5 times(dependant on their length whuch we have...

    No...it is a bit tricky here,s the deal since OP is a common side side we just need to find the ratio of their heights right... Since ba and op are paralle their HEIGHT component can be expressed as their ratio of lengths in general(if u wud like I will provide a detailed expl abt this) so it...

    In the locus questions when they usually ask us to define a region by giving three restrains on the region,they ask in condition for instance tht the region should be less than 3 cm from a point .then are we to draw a dotted line tht encloses the region(cos region is before 3 cm and the boundary...

    like I said the pivot is IN the rule with the ruler material both above and below it...So if a there is greater upward force it will push against the bottom the rule surface to create the downward force for equilibrium

    How was paper went of CHEMISTRY 5070/22

    Wht was the question exactly?..was it ionic equation for the reaction(CaOH2 +ammonium phosphate) or neutralization reaction

    lol swap erre..most common script error Yar after all my deliberation,i have found tht the whole idea on which they base their answer is rather vague,at least to me...there has to be a greater clue in the question or perhaps they shud specify in the syllabus this part or I dunno sth like this. I...

    http://papers.xtremepapers.com/CIE/Cambridge%20International%20O%20Level/Physics%20(5054)/5054_s11_qp_22.pdfThe question does not mention anything of the sort...Just check...Also if we do consider in any other question abt focal length then even then...........in fact it will be a whole other...

    so thts the fountainhead of ur misconception yar points do not always converge at focal point..Infact they rarely converge at f infact in practicals they converge very close coz theoretically tht,s not completely possible..It,s not the focal point...check the site does the image form at focal pt?

    Yar ...we get the first point of contact by passing ray undeviated thru the cdntre...We now get out first point..NOW all the rays frm tht point will converge at tht point which they illustrated in tht site....So it does not matter whether we know abt refr index or not...I don't want or like to...
