http://papers.xtremepapers.com/CIE/Cambridge International O Level/Physics (5054)/5054_w08_ms_4.pdf question 3b...has the ms gone nuts????? it shld b 28/8...

i dint get u the reading would be 1.28 and the final ans 0.16 thats what i think

 

[usama321]

force from fuel is 3.2*10^7N. what will be the resultant force and why? marking scheme says 4.8*10^7 Suchal Riaz

what papers is this? i think you are missing the whole question. The resultant force is the sum of all the forces in a system, and you are not showing the whole question

yup as the paper is folded three times, we are actually measuring the thickness of four papers. So, we divide 1.28/8, and that is 0.16

i know now what they are saying. They asked to show your working clearly. So 28 is the reading on the second scale and we have to show it as asked by the question

When its not specified in the m.s my teacher gives half the marks for labelling and half for drawing. To be on safe side, I suggest you always write all the labels visible disregarding the marks. In this diagram you can label the testa/seed coat, endosperm/cotyledon, and plumule(unshaded part on the top).
